Acceleration
Definition
The rate of change of velocity with respect to time.
Acceleration is a vector quantity as it has both magnitude and direction.
Formula of Acceleration : –
S I unit of acceleration m/s2 or , ms-1
CGS unit of acceleration cm/s2 or , cms-1
Types of accelerations
Uniform and Non-uniform acceleration
Average acceleration
The average acceleration over a period of time is defined as the total change in velocity is divided by the total time taken . For a given interval of time, it is denoted as ā.
Mathematically,
Where v2 and v1 are the instantaneous velocities at time t2 and t1 and ā is the average acceleration
