Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force and the application of force is the point where force is applied. Push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. Terms like stretch and squeeze can also be used to denote force.
In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity.
Derivations from other quantities: F = m a (mass×acceleration)

SI Unit : Newton/kgm/s2
