non conservative forces equation

How do you determine if a force is conservative?
Identify all forces acting on the body or bodies. Determine whether each force that does work is conservative. If a non-conservative force (e.g., friction) is doing work, then mechanical energy is not conserved. The system must then be analyzed with non-conservative work, Equation 8.13.
What is an example of a nonconservative force?
A nonconservative force is one for which work depends on the path. Friction is an example of a nonconservative force that changes mechanical energy into thermal energy. Work done by a nonconservative force changes the mechanical energy of a system. In equation form, or, equivalently,
Why is there no potential energy associated with nonconservative forces?
Because of this dependence on path, there is no potential energy associated with nonconservative forces. An important characteristic is that the work done by a nonconservative force adds or removes mechanical energy from a system. Friction, for example, creates thermal energy that dissipates, removing energy from the system.
Does work done by nonconservative forces equal the change in mechanical energy?
We will see that the work done by nonconservative forces equals the change in the mechanical energy of a system. As noted in Kinetic Energy and the Work-Energy Theorem, the work-energy theorem states that the net work on a system equals the change in its kinetic energy, or Wnet = ΔKE W net = ΔKE.
