MCQ's Based on Motion

1) Which of the following is a scalar quantity?
A. Velocity
B. Force
C. Displacement
D. Speed

Answer: D. Speed

Explanation: Scalar quantities are the ones which have only magnitude and no direction. Speed is a scalar quantity as it only specifies the magnitude of the velocity.

2) Which of the following is a vector quantity?
A. Temperature
B. Mass
C. Acceleration
D. Energy

Answer: C. Acceleration

Explanation: Vector quantities are the ones which have both magnitude and direction. Acceleration is a vector quantity as it specifies both magnitude and direction of the change in velocity.

3) Which of the following represents the correct formula for velocity?
A. v = d/t
B. v = a*t
C. v = F/m
D. v = d/t + 1/2*a*t^2

Answer: A. v = d/t

Explanation: Velocity is defined as the displacement per unit time. Therefore, the correct formula for velocity is v = d/t.

4) Which of the following represents the correct formula for acceleration?
A. a = v/t
B. a = F/m
C. a = d/t
D. a = v^2/d

Answer: B. a = F/m

Explanation: Acceleration is defined as the change in velocity per unit time. Therefore, the correct formula for acceleration is a = F/m, where F is the force applied and m is the mass of the object.

5) Which of the following represents the correct formula for displacement?
A. d = v*t
B. d = a*t
C. d = F/m
D. d = 1/2*a*t^2

Answer: D. d = 1/2*a*t^2

Explanation: Displacement is defined as the change in position of an object from its initial position. Therefore, the correct formula for displacement is d = 1/2*a*t^2, where a is the acceleration and t is the time taken.

6) Which of the following represents uniform motion?
A. A car accelerating from rest
B. A pendulum swinging back and forth
C. A train moving at a constant speed
D. A ball thrown upwards

Answer: C. A train moving at a constant speed

Explanation: Uniform motion is when an object moves at a constant velocity, i.e., with constant speed and direction. A train moving at a constant speed represents uniform motion.

7) Which of the following represents non-uniform motion?
A. An object moving at a constant speed in a straight line
B. A car accelerating from rest
C. A ball rolling down a hill
D. A pendulum swinging back and forth

Answer: B. A car accelerating from rest

Explanation: Non-uniform motion is when an object moves with varying speed or direction. A car accelerating from rest represents non-uniform motion.

8) Which of the following represents the correct formula for force?
A. F = m*a
B. F = m/v
C. F = d/t
D. F = v^2/d

Answer: A. F = m*a

Explanation: Force is defined as the push or pull on an object that changes its state of motion. Therefore, the correct formula for force is F = m*a, where m is

prove that an object in motion can also be in rest at the same time.its not mcq but its good
