Answer 1

Answer:

The physical quantity which causes motion in a body is Force.

And the SI unit of Force is Newton. A force is any interaction which tends to change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described by intuitive concepts such as a push or a pull.
