Force is the push or pull on an object. A force causes its state of rest or uniform motion or its shape. Force is a vector quantity, which means it has both magnitude and direction. A force is an action on a body. It causes acceleration. Note: The rate of change of momentum is directly proportional to the applied force.

To change the magnitude of velocity of an object

To change direction of motion of an object
