Example Grade 9 Physics Questions with Detailed Answers and Explanations

To enhance understanding, here are three example Grade 9 physics questions with detailed answers and explanations, covering fundamental concepts in physics.

Grade 9 Physics Tutoring Question 1: Newton’s Second Law of Motion

Problem:
A 5 kg object is subjected to a force of 20 N. Calculate the acceleration of the object.

Solution:

To solve this problem, we use Newton’s Second Law of Motion, which states that the force $(( F ))$ acting on an object is equal to the mass $(( m ))$ of the object multiplied by its acceleration $(( a ))$ :

$[ F = m \cdot a ]$

Here, $( F = 20 \, \text{N} )$ and $( m = 5 \, \text{kg} )$ . We need to find $( a )$ .

Rearrange the formula to solve for acceleration:

$[ a = \frac{F}{m} ]$

Substitute the given values:

$[ a = \frac{20 \, \text{N}}{5 \, \text{kg}} = 4 \, \text{m/s}^2 ]$

Explanation:

Newton’s Second Law of Motion indicates that acceleration is directly proportional to the force applied and inversely proportional to the mass of the object. In this case, the force is 20 N and the mass is 5 kg. Dividing the force by the mass gives us the acceleration. So, with a force of 20 N applied to a 5 kg object, the object accelerates at $( 4 \, \text{m/s}^2 )$ .

Answer:
The acceleration of the object is $( 4 \, \text{m/s}^2 )$ .

Grade 9 Physics Tutoring Question 2: Work Done and Energy

Problem:
If a force of 10 N is used to move an object 3 meters in the direction of the force, calculate the work done.

Solution:

Work done $(( W ))$ is calculated using the formula:

$[ W = F \cdot d ]$

where:

( F ) is the force applied (10 N),
( d ) is the distance over which the force is applied (3 m).

Substitute the given values:

$[ W = 10 \, \text{N} \times 3 \, \text{m} = 30 \, \text{J} ]$

Explanation:

Work is defined as the product of the force applied to an object and the distance over which the force is applied. It measures how much energy is transferred when a force moves an object. Here, a force of 10 N is applied over a distance of 3 meters, so the work done is $( 30 \, \text{J} )$ (Joules). This result represents the amount of energy transferred to the object.

Answer:
The work done is $( 30 \, \text{J} )$ (Joules).

Grade 9 Physics Tutoring Question 3: Speed and Velocity

Problem:
A car travels 120 kilometers in 2 hours. Calculate the average speed of the car.

Solution:

Average speed (( v )) is calculated using the formula:

$[ v = \frac{d}{t} ]$

where:

( d ) is the distance traveled (120 km),
( t ) is the time taken (2 hours).

Substitute the given values:

$[ v = \frac{120 \, \text{km}}{2 \, \text{hours}} = 60 \, \text{km/h} ]$

Explanation:

Average speed is defined as the total distance traveled divided by the total time taken. It gives an idea of how fast an object is moving over a period. Here, the car travels a distance of 120 km in 2 hours. By dividing the distance by the time, we find the average speed of the car to be ( 60 \, \text{km/h} ). This tells us that, on average, the car travels 60 kilometers each hour.

Answer:
The average speed of the car is $( 60 \, \text{km/h} )$ .

These questions and answers are designed to help Grade 9 students understand key concepts in physics, including Newton’s laws, work done, and average speed. Detailed explanations provide clarity on how the principles are applied to solve problems, reinforcing the learning process.

Example Grade 10 Physics Questions with Detailed Answers and Explanations

Grade 10 physics introduces students to more complex concepts, such as kinematics, dynamics, and energy. Here are three example questions at this level, each with detailed answers and explanations.

Grade 10 Physics Tutoring Question 1: Kinematic Equations

Problem:
A car accelerates from rest at a constant rate of $( 3 \, \text{m/s}^2 )$ for ( 8 ) seconds. Calculate the final velocity of the car and the distance traveled during this time.

Solution:

To solve this problem, we will use two kinematic equations:

Final Velocity Calculation: The formula to find the final velocity (( v )) when starting from rest is: $[ v = u + a \cdot t ]$ where:

( u ) is the initial velocity (0 m/s, since the car starts from rest),
( a ) is the acceleration $(( 3 \, \text{m/s}^2 ))$ ,
( t ) is the time $(( 8 ) s)$ . Substituting the values: $[ v = 0 \, \text{m/s} + 3 \, \text{m/s}^2 \cdot 8 \, \text{s} = 24 \, \text{m/s} ]$

Distance Traveled Calculation: The formula to find the distance traveled $(( s ))$ is:

$[ s = u \cdot t + \frac{1}{2} a \cdot t^2 ]$

Substituting the values:

$[ s = 0 \, \text{m/s} \cdot 8 \, \text{s} + \frac{1}{2} \cdot 3 \, \text{m/s}^2 \cdot (8 \, \text{s})^2 ]$

$[ s = \frac{1}{2} \cdot 3 \cdot 64 = 96 \, \text{m} ]$

Explanation:

The final velocity is calculated using the equation that relates initial velocity, acceleration, and time. Since the car starts from rest, the initial velocity is zero. The distance traveled is calculated using the formula for uniformly accelerated motion, which includes both the initial velocity term (which is zero here) and the term for acceleration.

Answer:

The final velocity of the car is $( 24 \, \text{m/s} )$ .
The distance traveled is $( 96 \, \text{m} )$ .

Grade 10 Physics Tutoring Question 2: Conservation of Energy

Problem:
A ball of mass $( 0.5 \, \text{kg} )$ is dropped from a height of $( 10 \, \text{m} )$ . Calculate the velocity of the ball just before it hits the ground and the kinetic energy it has at that point.

Solution:

Velocity Calculation Using Conservation of Energy: The potential energy (PE) at the height is converted into kinetic energy (KE) just before the ball hits the ground. The formula for potential energy is: $[ PE = m \cdot g \cdot h ]$ where:

( m ) is the mass $(( 0.5 \, \text{kg} ))$ ,
( g ) is the acceleration due to gravity $(( 9.8 \, \text{m/s}^2 ))$ ,
( h ) is the height $(( 10 \, \text{m} ))$ .
$[ PE = 0.5 \, \text{kg} \cdot 9.8 \, \text{m/s}^2 \cdot 10 \, \text{m} = 49 \, \text{J} ]$

This potential energy is equal to the kinetic energy just before impact:

$[ KE = \frac{1}{2} m \cdot v^2 ]$

Set ( PE ) equal to ( KE ) to find ( v ):

$[ 49 \, \text{J} = \frac{1}{2} \cdot 0.5 \, \text{kg} \cdot v^2 ]$

$[ 49 = 0.25 \cdot v^2 ]$

$[ v^2 = \frac{49}{0.25} = 196 ]$

$[ v = \sqrt{196} = 14 \, \text{m/s} ]$

Kinetic Energy Calculation: Substitute ( v ) into the kinetic energy formula:

$[ KE = \frac{1}{2} \cdot 0.5 \, \text{kg} \cdot (14 \, \text{m/s})^2 ]$

$[ KE = 0.25 \cdot 196 = 49 \, \text{J} ]$

Explanation:

The problem uses the principle of conservation of energy, where the potential energy due to height is converted into kinetic energy. By equating potential energy to kinetic energy, we solve for the velocity. The kinetic energy formula then confirms the energy just before impact.

Answer:

The velocity of the ball just before it hits the ground is $( 14 \, \text{m/s} )$ .
The kinetic energy at that point is $( 49 \, \text{J} )$ (Joules).

Grade 10 Physics Tutoring Question 3: Circular Motion

Problem:
A car travels in a circular track with a radius of $( 50 \, \text{m} )$ at a constant speed of $( 20 \, \text{m/s} )$ . Calculate the centripetal acceleration of the car.

Solution:

The formula for centripetal acceleration $(( a_c ))$ is:

$[ a_c = \frac{v^2}{r} ]$

where:

( v ) is the speed of the car $(( 20 \, \text{m/s} ))$ ,
( r ) is the radius of the track $(( 50 \, \text{m} ))$ .

Substitute the given values:

$[ a_c = \frac{(20 \, \text{m/s})^2}{50 \, \text{m}} = \frac{400}{50} = 8 \, \text{m/s}^2 ]$

Explanation:

Centripetal acceleration is the acceleration directed towards the center of the circular path, which keeps the object moving in a circle. It depends on the square of the speed and the radius of the circle. By substituting the given speed and radius into the formula, we calculate the centripetal acceleration.

Answer:

The centripetal acceleration of the car is $( 8 \, \text{m/s}^2 )$ .

These questions cover essential concepts in Grade 10 physics, including kinematics, energy conservation, and circular motion. Detailed explanations help to clarify the application of these concepts and reinforce the learning process.

Example Grade 11 Physics Questions with Detailed Answers and Explanations

Grade 11 physics often delves into more advanced topics, including Newtonian mechanics, energy, and electricity. Here are three example questions at this level, each with detailed answers and explanations.

Grade 11 Physics Tutoring Question 1: Newton’s Laws and Force

Problem:
A block of mass $( 5 \, \text{kg} )$ is placed on a frictionless surface. A force of $( 20 \, \text{N} )$ is applied horizontally to the block. Calculate the acceleration of the block and the distance it travels in ( 4 ) seconds.

Solution:

Acceleration Calculation: Using Newton’s Second Law of Motion: $[ F = m \cdot a ]$ where:

( F ) is the applied force $(( 20 \, \text{N} ))$ ,
( m ) is the mass of the block $(( 5 \, \text{kg} ))$ ,
( a ) is the acceleration. Rearranging to solve for acceleration: $[ a = \frac{F}{m} = \frac{20 \, \text{N}}{5 \, \text{kg}} = 4 \, \text{m/s}^2 ]$

Distance Traveled Calculation: The formula to find the distance traveled (( s )) when starting from rest is:

$[ s = \frac{1}{2} a \cdot t^2 ]$ where:

( a ) is the acceleration $(( 4 \, \text{m/s}^2 ))$ ,
( t ) is the time $(( 4 ) s)$ .

Substituting the values:

$[ s = \frac{1}{2} \cdot 4 \, \text{m/s}^2 \cdot (4 \, \text{s})^2 ]$

$[ s = \frac{1}{2} \cdot 4 \cdot 16 = 32 \, \text{m} ]$

Explanation:

Using Newton’s Second Law, we find the acceleration by dividing the force by the mass. With acceleration known, we use the kinematic equation for distance, assuming the block starts from rest. The calculation shows how the block accelerates and covers a distance due to the applied force.

Answer:

The acceleration of the block is $( 4 \, \text{m/s}^2 )$ .
The distance traveled in ( 4 ) seconds is $( 32 \, \text{m} )$ .

Grade 11 Physics Tutoring Question 2: Conservation of Momentum

Problem:
A $( 2 \, \text{kg} )$ cart moving with a velocity of $( 5 \, \text{m/s} )$ collides elastically with a stationary $( 3 \, \text{kg} )$ cart. After the collision, the $( 2 \, \text{kg} )$ cart moves with a velocity of $( 2 \, \text{m/s} )$ . Find the final velocity of the $( 3 \, \text{kg} )$ cart.

Solution:

Use Conservation of Momentum: The total momentum before and after the collision must be the same. The formula for momentum $(( p ))$ is: [/latex][ p = m \cdot v ][/latex]

Initial momentum of the $( 2 \, \text{kg} )$ cart:

$( p_{1i} = 2 \, \text{kg} \cdot 5 \, \text{m/s} = 10 \, \text{kg} \cdot \text{m/s} )$
Initial momentum of the $( 3 \, \text{kg} )$ cart:

$( p_{2i} = 3 \, \text{kg} \cdot 0 \, \text{m/s} = 0 \, \text{kg} \cdot \text{m/s} )$

Total initial momentum:

$[ p_{\text{total,i}} = p_{1i} + p_{2i} = 10 + 0 = 10 \, \text{kg} \cdot \text{m/s} ]$
Final momentum of the $( 2 \, \text{kg} )$ cart:

$( p_{1f} = 2 \, \text{kg} \cdot 2 \, \text{m/s} = 4 \, \text{kg} \cdot \text{m/s} )$

Let $( v_{2f} )$ be the final velocity of the $( 3 \, \text{kg} )$ cart.

Then: $[ p_{2f} = 3 \, \text{kg} \cdot v_{2f} ]$

Total final momentum: $[ p_{\text{total,f}} = p_{1f} + p_{2f} = 4 + 3 \cdot v_{2f} ]$

By conservation of momentum:

$[ p_{\text{total,i}} = p_{\text{total,f}} ]$

$[ 10 = 4 + 3 \cdot v_{2f} ]$

$[ 3 \cdot v_{2f} = 6 ]$

$[ v_{2f} = \frac{6}{3} = 2 \, \text{m/s} ]$

Explanation:

Momentum conservation is applied, where the total momentum before the collision equals the total momentum after the collision. By setting up the equation and solving for the unknown velocity of the second cart, we determine how the momentum is distributed after the collision.

Answer:

The final velocity of the $( 3 \, \text{kg} )$ cart is [/latex]( 2 \, \text{m/s} )[/latex].

Grade 11 Physics Tutoring Question 3: Electrical Circuits

Problem:
A circuit consists of a $( 12 \, \text{V} )$ battery connected in series with a $( 6 \, \text{Ω} )$ resistor and a $( 3 \, \text{Ω} )$ resistor. Calculate the total current flowing through the circuit and the voltage drop across each resistor.

Solution:

Calculate Total Resistance: In a series circuit, the total resistance $(( R_{\text{total}} ))$ is the sum of the individual resistances:

$[ R_{\text{total}} = R_1 + R_2 ]$

$[ R_{\text{total}} = 6 \, \text{Ω} + 3 \, \text{Ω} = 9 \, \text{Ω} ]$
Calculate Total Current:

Using Ohm’s Law:

$[ I = \frac{V}{R_{\text{total}}} ]$ where:

( V ) is the voltage of the battery $(( 12 \, \text{V} ))$ ,
$( R_{\text{total}} )$ is the total resistance $(( 9 \, \text{Ω} ))$ .

Substituting the values:

$[ I = \frac{12 \, \text{V}}{9 \, \text{Ω}} = \frac{4}{3} \, \text{A} \approx 1.33 \, \text{A} ]$

Calculate Voltage Drop Across Each Resistor: Using Ohm’s Law for each resistor:

For the $( 6 \, \text{Ω} )$ resistor:

$[ V_1 = I \cdot R_1 ]$

$[ V_1 = 1.33 \, \text{A} \cdot 6 \, \text{Ω} = 8 \, \text{V} ]$
For the $( 3 \, \text{Ω} )$ resistor:

$[ V_2 = I \cdot R_2 ]$

$[ V_2 = 1.33 \, \text{A} \cdot 3 \, \text{Ω} = 4 \, \text{V} ]$

Explanation:

In a series circuit, the total resistance is the sum of the resistances, which affects the total current flowing through the circuit. By applying Ohm’s Law, we calculate both the total current and the voltage drop across each resistor.

Answer:

The total current flowing through the circuit is $( \frac{4}{3} \, \text{A} )$ or approximately $( 1.33 \, \text{A} )$ .
The voltage drop across the $( 6 \, \text{Ω} )$ resistor is [/latex]( 8 \, \text{V} )[/latex].
The voltage drop across the $( 3 \, \text{Ω} )$ resistor is [/latex]( 4 \, \text{V} )[/latex].

These questions cover fundamental concepts in Grade 11 physics, including Newtonian mechanics, conservation of momentum, and electrical circuits. Detailed explanations ensure a clear understanding of the principles and calculations involved.

Advanced Grade 12 Physics Questions with Detailed Answers and Explanations

Grade 12 physics explores complex topics such as quantum mechanics, electromagnetism, and advanced mechanics. Here are three advanced questions with comprehensive answers and explanations.

Grade 12 Physis Tutoring Question 1: Quantum Mechanics – Photoelectric Effect

Problem:
The work function of a metal is $( 2.5 \, \text{eV} )$ . Light of wavelength $( 400 \, \text{nm} )$ is incident on the metal. Calculate the maximum kinetic energy of the emitted photoelectrons and their velocity.

Solution:

Calculate the Energy of the Incident Photon:

The energy ( E ) of a photon is given by:

$[ E = \frac{hc}{\lambda} ]$ where:

( h ) is Planck’s constant $(( 6.626 \times 10^{-34} \, \text{J} \cdot \text{s} ))$ ,
( c ) is the speed of light $(( 3.0 \times 10^8 \, \text{m/s} ))$ ,
$( \lambda )$ is the wavelength $(( 400 \, \text{nm} = 400 \times 10^{-9} \, \text{m} ))$ .

Substituting the values:

$[ E = \frac{6.626 \times 10^{-34} \, \text{J} \cdot \text{s} \times 3.0 \times 10^8 \, \text{m/s}}{400 \times 10^{-9} \, \text{m}} ]$

$[ E = \frac{1.9878 \times 10^{-25}}{400 \times 10^{-9}} ]$

$[ E = 4.97 \times 10^{-19} \, \text{J} ]$

Converting this energy to electron volts $(1 eV = ( 1.602 \times 10^{-19} \, \text{J} ))$ :

$[ E = \frac{4.97 \times 10^{-19} \, \text{J}}{1.602 \times 10^{-19} \, \text{J/eV}} \approx 3.10 \, \text{eV} ]$

Calculate the Maximum Kinetic Energy of the Photoelectrons:

The maximum kinetic energy $( K_{\text{max}} )$ is given by:

$[ K_{\text{max}} = E_{\text{photon}} - \text{Work Function} ]$

$[ K_{\text{max}} = 3.10 \, \text{eV} - 2.5 \, \text{eV} = 0.60 \, \text{eV} ]$

Converting this energy to joules:

$[ K_{\text{max}} = 0.60 \, \text{eV} \times 1.602 \times 10^{-19} \, \text{J/eV} ]$

$[ K_{\text{max}} = 9.61 \times 10^{-20} \, \text{J}$
Calculate the Velocity of the Photoelectrons:

Using the kinetic energy formula:

$[ K_{\text{max}} = \frac{1}{2} m v^2 ]$

Solving for velocity ( v ), where ( m ) is the mass of an electron $(( 9.11 \times 10^{-31} \, \text{kg} ))$ :

$[ v = \sqrt{\frac{2 K_{\text{max}}}{m}} ]$

$[ v = \sqrt{\frac{2 \times 9.61 \times 10^{-20} \, \text{J}}{9.11 \times 10^{-31} \, \text{kg}}} ]$

$[ v = \sqrt{2.11 \times 10^{11}} ]$

$[ v \approx 1.45 \times 10^5 \, \text{m/s} ]$

Explanation:

First, the energy of the incident photons is calculated using the wavelength and Planck’s constant. The difference between this photon energy and the work function gives the maximum kinetic energy of the emitted electrons. The velocity is then computed from this kinetic energy using the standard kinetic energy formula.

Answer:

The maximum kinetic energy of the emitted photoelectrons is $( 0.60 \, \text{eV} )$ or $( 9.61 \times 10^{-20} \, \text{J} )$ .
The velocity of the photoelectrons is approximately $( 1.45 \times 10^5 \, \text{m/s} )$ .

Grade 12 Physics Tutoring Question 2: Electromagnetic Induction

Problem:
A coil with 100 turns and an area of $( 0.02 \, \text{m}^2 )$ is placed in a magnetic field that changes uniformly from $( 0 \, \text{T} )$ to $( 0.5 \, \text{T} )$ in $( 0.1 \, \text{s} )$ . Calculate the induced EMF in the coil.

Solution:

Calculate the Change in Magnetic Flux:

Magnetic flux $( \Phi )$ is given by:

$[ \Phi = B \cdot A ]$ where:

( B ) is the magnetic field,
( A ) is the area of the coil.

The change in flux $( \Delta \Phi )$ is:

$[ \Delta \Phi = \Phi_{\text{final}} - \Phi_{\text{initial}} ]$

$[ \Delta \Phi = (B_{\text{final}} \cdot A) - (B_{\text{initial}} \cdot A) ]$

$[ \Delta \Phi = (0.5 \, \text{T} \cdot 0.02 \, \text{m}^2) - (0 \cdot 0.02 \, \text{m}^2) ]$

$[ \Delta \Phi = 0.01 \, \text{Wb} ]$

Calculate the Induced EMF:

Faraday’s Law states:

$[ \text{EMF} = -N \frac{\Delta \Phi}{\Delta t} ]$ where:

( N ) is the number of turns (100),
$( \Delta t )$ is the time interval $(( 0.1 \, \text{s} ))$ .

Substituting the values:

$[ \text{EMF} = -100 \times \frac{0.01 \, \text{Wb}}{0.1 \, \text{s}} ]$

$[ \text{EMF} = -100 \times 0.1 \, \text{V} ]$

$[ \text{EMF} = -10 \, \text{V} ]$

Explanation:

The magnetic flux through the coil changes as the magnetic field changes. By applying Faraday’s Law, the induced EMF is calculated from the rate of change of this flux. The negative sign indicates the direction of the induced EMF as per Lenz’s Law, but the magnitude is typically of interest in these calculations.

Answer:

The induced EMF in the coil is $( 10 \, \text{V} )$ (magnitude).

Grade 12 Physics Tutoring Question 3: Rotational Dynamics

Problem:
A solid disk with a mass of $( 2 \, \text{kg} )$ and a radius of $( 0.5 \, \text{m} )$ rotates about its central axis with an angular velocity of $( 10 \, \text{rad/s} )$ . Calculate the rotational kinetic energy of the disk.

Solution:

Calculate the Moment of Inertia: For a solid disk rotating about its central axis, the moment of inertia ( I ) is: $[ I = \frac{1}{2} m r^2 ]$ where:

( m ) is the mass of the disk $(( 2 \, \text{kg} ))$ ,
( r ) is the radius $(( 0.5 \, \text{m} ))$ .

Substituting the values:

$[ I = \frac{1}{2} \cdot 2 \, \text{kg} \cdot (0.5 \, \text{m})^2 ]$

$[ I = \frac{1}{2} \cdot 2 \cdot 0.25 ]$

$[ I = 0.25 \, \text{kg} \cdot \text{m}^2 ]$

Calculate the Rotational Kinetic Energy:

The rotational kinetic energy $( K_{\text{rot}} )$ is given by:

$[ K_{\text{rot}} = \frac{1}{2} I \omega^2 ]$ where:

$( \omega )$ is the angular velocity $(( 10 \, \text{rad/s} ))$ .

Substituting the values:

$[ K_{\text{rot }} = \frac{1}{2} \cdot 0.25 \, \text{kg} \cdot \text{m}^2 \cdot (10 \, \text{rad/s})^2 ]$

$[ K_{\text{rot}} = \frac{1}{2} \cdot 0.25 \cdot 100 ]$

$[ K_{\text{rot}} = 12.5 \, \text{J} ]$

Explanation:

The moment of inertia for a rotating solid disk is calculated based on its mass and radius. Using this moment of inertia, the rotational kinetic energy is then computed from the angular velocity. This reflects the energy due to the rotation of the disk.

Answer:

The rotational kinetic energy of the disk is $( 12.5 \, \text{J} )$ .
