Acceleration -

  • Rate of change of velocity with time.

  • Formula-

              a=change in velocity / change in time

                           a=\frac{v_{f}-v_{i}}{t}

  • Tips for Acceleration-

  1. It is a vector quantity

  2. Dimension = LT^{-2}

  3. S.I unit =  ms^{-2}

 

 

 

 

Acceleration = Change in velocity /Time

Change in velocity is due to change in direction and magnitude of the velocity
