Question

Define average acceleration and instantaneous acceleration.

Answer 1

Answer :-

 Average acceleration is the change in velocity divided by an elapsed time.

Instantaneous acceleration is defined as the limit of the average acceleration when the interval of time considered approaches 0.

Answer 2

${\huge{\mathfrak{Answer}}}$

This can mean a change in the object's speed or direction. Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. Constant or uniform acceleration is when the velocity changes the same amount in every equal time period
