☛ Acceleration:- It is defined as rate of change of velocity with respect to time.

• SI unit of acceleration is m/s².

• CGS unit of acceleration is cm/s².

• It is a vector quantity.

✵ Types of acceleration

☛ Uniform acceleration:- If a body change it's velocity by equal amount in equal intervals of time, then body is said to be moving with uniform acceleration.

☛ Non Uniform acceleration:-If a body change it's velocity by unequal amount in equal intervals of time then body is said to be moving with non uniform acceleration.
