In physics, a conservative force is a force with the property that the total work done in moving a particle between two points is independent of the path taken. Equivalently, if a particle travels in a closed loop, the total work done (the sum of the force acting along the path multiplied by the displacement) by a conservative force is zero. A conservative force depends only on the position of the object. If a force is conservative, it is p… WebAug 11, 2024 · Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from the system as the system progresses, …
