what is fource
A force can be a push or a pull. It is not something you can see or touch, but can see it in action. Forces can be measured using a device called force meter. The unit of force is called the newton. It is represented by the symbol N. 

A force usually results from an interaction. The interaction can be a physical one, or a non-physical one. Forces resulting from physical interaction are called 'Contact Forces' and examples include Frictional, Tension, Air resistance and Spring force.

A force resulting from non-physical interaction is called
'Action-at-a-distance force' and examples include gravitational, electrical or magnetic force.
