Two objects must interact for force to come into play

 

Example 1

A person standing behind a car does not make car move

But when a person pushes the car,he makes car move

We can say that when there is an interaction between the person and car,only then car moves

 


Person Standing behind car

No interaction so no force

Person Pushing car

Interaction between Person and car, So Car moves

Example 2


If a football player just stands near the football,the football does not move

When he kicks the football,it moves

We can say that there is interaction between football player and ball,only then ball moves
