Here are 30 multiple-choice model physics questions for grade 12, with explanations:
1. What is the relationship between the frequency (f) and wavelength (λ) of a wave?
a) f = c/λ
b) f = λ/c
c) f = c × λ
d) f = 1/λ
Explanation: The correct answer is a) f = c/λ, where c is the speed of the wave. This relationship is known as the wave equation and is derived from the fact that the speed of a wave is equal to the product of its frequency and wavelength.
2. A car is moving in uniform circular motion. Which of the following quantities is constant?
a) Velocity
b) Acceleration
c) Displacement
d) Speed
Explanation: The correct answer is d) Speed. In uniform circular motion, the speed (magnitude of the velocity) remains constant, while the direction of the velocity changes continuously, resulting in a constant acceleration directed towards the center of the circle, known as centripetal acceleration.
3. Which of Newton's laws of motion explains the concept of inertia?
a) First law
b) Second law
c) Third law
d) All of the above
Explanation: The correct answer is a) First law. Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion, unless acted upon by an unbalanced force.
4. A simple pendulum is used to measure the acceleration due to gravity (g). Which of the following factors does not affect the period (T) of the pendulum?
a) Length of the pendulum
b) Mass of the pendulum bob
c) Amplitude of the swing
d) Latitude of the location
Explanation: The correct answer is b) Mass of the pendulum bob. The period of a simple pendulum is given by the formula T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity. The mass of the pendulum bob does not affect the period.
5. A ball is thrown upwards with an initial velocity (v0). Which of the following quantities is not constant during the motion?
a) Potential energy
b) Kinetic energy
c) Total energy
d) Acceleration
Explanation: The correct answer is b) Kinetic energy. As the ball moves upwards, its kinetic energy decreases due to the decrease in velocity, while its potential energy increases. However, the total energy (the sum of kinetic and potential energy) remains constant, assuming no air resistance.
6. The work done by a constant force (F) acting on an object that moves a distance (d) in the direction of the force is given by:
a) W = F × d
b) W = F × d × cos(θ)
c) W = F × d × sin(θ)
d) W = F² × d
Explanation: The correct answer is a) W = F × d. The work done by a constant force is equal to the product of the force and the displacement in the direction of the force, regardless of the angle between the force and the displacement.
7. Which of the following statements about the laws of thermodynamics is true?
a) The first law states that energy can be created or destroyed.
b) The second law states that the entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.
c) The third law states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
d) All of the above
Explanation: The correct answer is c) The third law states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. The first law states that energy can be transformed but not created or destroyed, and the second law states that the entropy of an isolated system not in equilibrium will tend to increase over time.
8. Two waves with the same amplitude and frequency interfere constructively. What is the resulting amplitude of the combined wave?
a) Twice the amplitude of the individual waves
1. What is the relationship between the frequency (f) and wavelength (λ) of a wave?

a) Twice the amplitude of the individual waves
b) Half the amplitude of the individual waves
c) Equal to the amplitude of the individual waves
d) Four times the amplitude of the individual waves
