it is the speed of an object at a particular instant
what is speed ?
it is the distance travelled per unit time
what is velocity ?
it is the rate of change of displacement
what is the formula of speed ?
distance/ time
what is the formula of velocity ?
displacement/ time
what is acceleration "?
it is the rate of change of velocity

if two objects of the different masses fell from the same height, which object would fall faster ?
both objects would fall at the same rate of 10 m/s because of acceleration due to gravity
