This document defines force as a push or pull on an object that gives it energy to start moving, change direction, or stop moving. Forces are described by their strength and direction, and are measured in Newtons. There are two types of forces - contact forces that occur when objects touch, like pushes or pulls, and non-contact forces that act over a distance, like gravity or magnetism.
