Answer» ong>Answer: In PHYSICS, a force is any INTERACTION that, when unopposed, will change the motion of an object. 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 intuitively as a PUSH or a pull
