Given information
As we know that the conservative forces are the forces those store energy in the system and the forces those do not store energy in the system are called non-conservative forces. In another way, the work done by the forces is independent of the path taken by the object during its motion but depends only on end points are called conservative forces and the forces, work done by them depends on the path taken, are called non-conservative forces.
Step-by-step explanation
The forces, work done by them is independent of path means they store energy in the system like gravitational forces in which the work done against the gravity is stored in the system as potential energy but in the case of nonconservative forces the energy is dissipated in any another form and does not save in the system.
Some examples of the non-conservative forces are
(i) The upward force applied by us to a heavy book from a table to a high shelf in which the work done on the book by us is dependent on the path during its motion and the energy dissipates from the muscles in the form of heat and chemical energy. This force is non-conservative
(ii) The downward gravitational force in which the work done against the gravity is stored in the system as potential energy and path independent. This work done by the gravitational force is depends only on end points. This gravitational force is conservative in nature.
(iii) I air resistance is also exists while lifting up the book, this force is also non-conservative in nature. All these forces are shown in figure below.
