What is force?Force is the push or pull on an object resulting from the object's interaction with another object that causes it to change velocity (to accelerate). It is called an interaction because if one object acts on another, its action is matched by a reaction from the other object. This idea is known as Newton's third law.
InputJoule Per Meter is a unit of force equivalent to Newton. It is derived from the fact that work or kinetic energy change is force exerted through a distance.
Kilogram-force is a non-standard metric unit of force equal to the magnitude of the force exerted on one kilogram of mass under standard gravitational acceleration.
