Question

define acceleration

Answer 1

acceleration is the rate of change of velocity with respect to the time

Answer 2

When an object moves with changing velocity it's motion is called variable motion and change in velocity per unit time is called acceleration.
1."acceleration of a body on an object is defined as the rate of change of velocity of that object. "
2.the acceleration is defined as the change in velocity of an object per unit time. Acceleration = change in velocity /time taken
Rate of change of velocity =final velocity - initial velocity /time taken
Unit of acceleration is -
m/sec^2 in MKS
cm/sec^2 in CGS
