Question

what is accleration?​

Answer 1

Answer:

Acceleration can be defined as rate of change of velocity.

it's mathematical expression is

$\frac{v - u}{t}$

where v is final velocity

and i is initial velocity.

S.I unit of acceleration is

$\frac{m}{ {s}^{2} }$

Answer 2

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.
