Is friction force conservative or non-conservative?

Non-conservative The idea of a conservative force is that you can walk from one place to another and no matter what path you take it takes you the same amount of work to make the motion. read more

Conservative forces are easier to work with in physics because they don’t “leak” energy as you move around a path — if you end up in the same place, you have the same amount of energy. If you have to deal with nonconservative forces such as friction, including air friction, the situation is different. read more

Friction is NOT a conservative force. It is different from the fundamental forces in physics, which are all conservative, because friction is an effective force arising as a result of statistical mechanics (thermodynamics). A conservative force CONSERVES the total energy in the system. read more

Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force. Other examples of conservative forces are: force in elastic spring, electrostatic force between two electric charges, magnetic force between two magnetic poles. read more

If a body is under the action of a force that does no net work during any closed loop, then the force is conservative. If work is done, the force is nonconservative. In other words, a particle located at the same physical location in a closed loop must have the same kinetic energy at all times if it is within a conservative system. This fact is the fundamental definition of a conservative force. read more
