Question

what is acceleration? and write Si unit.​

Answer 1

Answer:

a) Acceleration can be defined as the rate of change of velocity with time. It can also be defined as the increase in velocity per second.

b)The S.I. unit of acceleration is meter per second square or ms−2.

Answer 2

$\huge\colorbox{pink}{Answer}$

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

SI unit of Acceleration - meter per second squared or m/s2
