WebSep 17, 2024 · A net force is defined as the sum of all the forces acting on an object. The equation below is the sum of N forces acting on an object. There may be several forces acting on an object, and when ... WebNewton’s first law says that a net external force causes a change in motion; thus, we see that a net external force causes nonzero acceleration. We defined external force in Forces as force acting on an object or system that originates outside of the object or system. Let’s consider this concept further.
