Force can also stop a moving body. The other effect is it can change the mation of the body by moving it faster or slower
On a daily basis, we walk, we run, we play, we sit or stand. In all of these activities, we are changing the state of motion. We are bringing some object to rest or bringing it in motion. What is this called? What’re we actually doing? We’re actually applying ‘Force’ while bringing the object to rest or in motion. But what is a force? What are the effects of force? Let us scroll down and find out.
A ‘Force’ is a vector quantity that can be described as a push or pull on an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, the objects experience an equal and opposing force on each other. In other words both the objects ‘exert force’ on each other. Force only exists as a result of an interaction. If there is no interaction, the objects no longer experience the force. Force is measured in units called Newtons (N), named after the famous scientist Sir Issac Newton.

Interactive Nature of Force
For force to exist, there must be an interaction between at least two objects. This interaction between the objects may or may not be physical. Pulling a rope or hitting a ball with a bat come physical interaction whereas forces like the magnetic force, electrostatic force, etc come under non-physical force.

A force has both magnitude and direction. The magnitude of the force expresses the strength of a force. To completely determine a force both direction and magnitude must be specified; since the direction or magnitude of the applied force changes its effects.
