Forces are said to be conservative in nature if work done against the forces gets conversed in the body in form of potential energy. Example:- gravitational forces, elastic forces & all the central forces
PROPERTIES OF CONSERVATIVE FORCES
- Work done against these forces is conserved & gets stored in the body in the form of P.E.
- Work done against these forces is never dissipated by being converted into non usable forms of energy like heat, light, sound etc.
- Work done against conservative forces is a state function & not path function i.e. Work done against it, depends only upon initial & final states of body & is independent of the path through which process has been carried out.
- Work done against conservative forces is zero in a complete cycle.
Non-Conservation forces
Non-conservative forces are the forces, work is done against which does not get conserved in the body in the form of potential energy.
PROPERTIES OF NON-CONSERVATIVE FORCES
- Work done against these forces does not get conserved in the body in the form of P.E.
- Work done against these forces is always dissipated by being converted into non-usable forms of energy like heat, light, sound etc.
- Work done against non-conservative force is a path function and not a state function.
- Work done against non-conservative force in a complete cycle is not zero.
