Force is an external push or pull that changes the state or shape of the object. Some of the changes that occur due to the application of force are as folllows:
1. Changes state:
Force can change the state of motion of an object. It can induce motion in a stationary object or even can stop a moving object. It can increase or decrease the speed of a moving object. It can also change the direction of the moving object. If the force applied on the object is in the direction of motion, the speed of the object increases. If the force is applied on the object, in a direction opposite to the direction of motion, then the speed of the object decreases.
2. Shape of the object:
Force can change the shape of the object on which it is applied. When force is applied, there is a change in the shape of the object which are sometimes visible and sometimes apparent.
For example, beating a metal can turn it into sheet.
