Question

____ is the rate of change in velocity.

Answer 1

The answer is acceleration

Answer 2

Answer : Acceleration is the rate of change in velocity.

Explanation :

Acceleration : It is defined as the rate of change in the velocity per unit time. Acceleration is a vector quantity that means it depends on the magnitude and the direction of an object. The S.I unit of acceleration is,
`m/s^2`

The formula of acceleration will be,

`Acceleration=\frac{\text{Change in velocity}}{\text{Time taken}}\\\\a=(v_(final)-v_(initial))/(t)`

Hence, acceleration is the rate of change in velocity.
