Explain primary concept of force.
Explain primary concept of force.
To bring stationary object in motion force is required. Similarly to slow down object in motion or to stop moving object force is required.
A ball is moving down along slope. By applying force in opposite direction it can be stopped. The external parameter (agency) by which can change state of motion or rest can be changed is called force.
Effect of force on a body can be following :
$(i)$ Force can bring body in rest to motion or body in motion to rest.
$(ii)$ It can increase or decrease speed of object.
$(iii)$ Force can change direction of motion of object.
$(iv)$ Force can change shape of an object.
