Acceleration Formula in Physics 

In Physics , Acceleration is described as the rate of change of Velocity of an object, irrespective of whether it speeds up or slows down. If it speeds up, Acceleration is taken as positive and if it slows down, the Acceleration is negative. It is caused by the net unbalanced force acting on the object, as per Newton’s Second Law. Acceleration is a vector quantity as it describes the time rate of change of Velocity, which is a vector quantity. Acceleration is denoted by a. Its SI unit is

ms2��2 and dimensions are

[M0L1T–2][�0�1�–2].

If

v0,vt�0,�� and t represents the initial Velocity, final Velocity and the time taken for the change in Velocity, then, the Acceleration is given by:

a→=vt→−v0→t�→=��→−�0→�

In one dimensional motion, we can use;

a=vt−v0t�=��−�0�
