what is f net

Net force is defined as the sum of all the forces acting on an object in a single plane. It can accelerate a mass and is important in describing the motion of an object. The formula for net force is FNet = F1 + F2 + F3 + ... + FN, where F1, F2, F3, and FN are the forces acting on the object. The direction of the net force is determined by the sign, with motion going backwards or down being negative and motion going forwards or up being positive. When the magnitude of the net force is non-zero, the object is either speeding up or slowing down, while a magnitude of zero means the object is either not moving or moving with a constant speed. The net force formula changes depending on whether the object is at rest or in motion. When the object is at rest, the net force formula is FNet = Fa + Fg, where Fa is the applied force and Fg is the gravitational force. When the object is in motion, the net force formula is FNet = Fa + Fg + Ff + FN, where Ff is the frictional force and FN is the normal force that balances the opposite force.
