Motion is the change in position of a body with time but, what exactly is the cause of motion?
The reason behind the motion of a body is force.
Force is defined as a push or pull which can cause a body to move, stop, change speed, or change direction.
It can also change the shape and size of a body. For example, the shape of a rubber band changes when stretched.
Some examples of force:
Frictional force: It opposes the motion when the surface of one body comes in contact with the other.
Gravitational force: It is the attractive force between two bodies with mass.
