Free Force and Motion MCQs with Answers
1,416 Force and Motion MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.

- A. Ball A
- B. Ball B
- C. Both ball A and B
- D. insufficient data
Explanation: The vertical acceleration is same for both balls due to gravitational acceleration which being the same for both balls.
Correct answer: Ball B- A. Tan^-1 (2)
- B. Tan^-1 (4)
- C. Tan^-1 (1)
- D. Tan^-1 (2/3)
Explanation: Here is the explanation of the correct option Current and voltage vary sinusoidal with same frequency and are in phase with each other

- B. 1.275 m.
- C. 2.551 m.
- D. 5.102 m.
Explanation: To find the maximum height attained by the projectile, first decompose the initial velocity into vertical and horizontal components.
Correct answer: 5.102 m.- A. A
- B. B
- C. C
- D. D
Explanation: The vertical component of the velocity of a projectile is maximum at the point of launch (point A) because it starts with its initial…
Correct answer: A- A. Linear motion.
- B. Circular motion.
- C. Projectile motion.
- D. Rotational motion.
Explanation: When a football is kicked into the air, it follows a curved trajectory known as projectile motion.
Correct answer: Projectile motion.- A. Zero.
- B. Half.
- C. Double.
- D. Maximum.
Explanation: In projectile motion, at the highest point of the trajectory, the projectile's vertical component of velocity is zero.
Correct answer: Zero.- A. Same size of balls
- B. Horizontal velocity.
- C. Same vertical height
- D. Horizontal acceleration
Explanation: The time it takes for an object to reach the ground is determined by its initial vertical velocity and the height from which it is…
Correct answer: Horizontal velocity.- A. Missile I
- B. Missile II
- C. Missile III
- D. Missile IV
Explanation: In projectile motion, the optimal angle for maximum range is 45°. Missiles launched at angles deviating from this will cover shorter…
Correct answer: Missile IV- A. Linear motion.
- B. Circular motion.
- C. Vibratory motion.
- D. Projectile motion.
Explanation: The correct answer is projectile motion. Projectile motion occurs when an object is thrown or projected into the air and moves along a…
Correct answer: Projectile motion.- A. Angle of projection of the athlete
- B. Acceleration of the athlete
- C. Body shape of the athlete
- D. Weight of the athlete
Explanation: A) Angle of projection of the athlete: In projectile motion (like a long jump or shot put, as depicted in the image), the angle at which…
Correct answer: Angle of projection of the athlete- A. 10m
- B. 20m
- C. 5m
- D. Insufficient information
Explanation: The correct answer is 20 according to the given solution For Motion under Gravity.
Correct answer: 20m- A. 17m
- B. 30 m
- C. 52 m
- D. 90 m
Explanation: Initial velocity = u= 10 m/s Final velocity = v = 0 m/s Distance covered = 10 m Acceleration of the bike: 2as= v²- u²2(a)(10) = 0² -…
Correct answer: 90 m- A. 9.8m/s2
- B. 98m/s2
- C. 980m/s2
- D. -9.8m/s2
Explanation: a = (Vf -Vi)/ ta = 0 - 98 / 10 = -9.8 m/s2.
Correct answer: -9.8m/s2- A. Force
- B. Acceleration
- C. Power
- D. Energy
Explanation: Acceleration is defined as the rate of change of velocity with respect to time.
Correct answer: Acceleration- A. 10kg
- B. 50kg
- C. Both have same velocity
- D. Cannot be calculated
Explanation: If we neglect air resistance both objects reach the ground at the same time so their velocity will be the same.
Correct answer: Both have same velocity- A. Positive x Axis
- B. Negative x Axis
- C. Positive y Axis
- D. Negative y Axis
Explanation: The negative acceleration (deceleration) opposes the car's motion along the positive x-axis.
Correct answer: Positive x Axis- A. Linear
- B. Quadratic
- C. Cubic
- D. Decreasing Linearly
Explanation: If the velocity of a particle is varying linearly with time, the shape of the d-t (displacement-time) curve would be:B.
Correct answer: Quadratic- A. negative
- B. positive
- C. constant
- D. zero
Explanation: Linear acceleration, also known as tangential acceleration, is zero when a body is moving in a circular path because the object has…
