To move a stationary object from one place to another, we need to put some effort. This effort is known as force. For Example, a push, a hit or a pull.


What happen after applying force?

  •  Initiate a motionless object.
  • Change (increase or decrease) in the velocity of the moving object.
  • Change in the direction of a moving object.
  • Change in the shape and size of an object.
