The rate of change of velocity with time is known as

A
impulse

B
momentum

C
acceleration

D
displacement

Solution

Acceleration is defined as the rate of change of velocity with time.

The correct answer is C.

Why alternative A is wrong:

The impulse of a constant force is the product of force and time during which it acts. Hence this alternative is incorrect.

Why alternative B is wrong:

Momentum is defined as the product of velocity and mass of a particle. Hence this alternative is incorrect.

Why alternative D is wrong:

The minimum distance between the final and initial position of a particle is known as displacement. Hence this alternative is incorrect.
