What is Force

What is Force :-

Force may be defined as an external agency (push or pull) which changes or tends to change the state of rest or of uniform motion or the direction of motion of a body.

or in other words….

Force is that physical quantity which produces or tends to produce acceleration in a body.

When the force acting on a body is balanced force, then the body either remains at rest or moves with constant velocity and if the force acting on the body is unbalanced that is the resultant force is not zero, then the body moves with accelerated motion in the direction of resultant force.
