Step 4: Consider the types of forces involved- Conservative Forces: The work done by conservative forces (like gravity) in a closed path is zero. However, if kinetic energy is increasing, the work done by conservative forces could still be positive if the path is not closed.- Non-Conservati...
Non-Conservative Forces:A non-conservative force is a force whose work done on a system is dependent on the path the objects within the system take. If an object in the presence of a non-conservative force were to take a path that starts and ends at the same location, the work done wi...

Physics EducationAs noted in C. Carnero, J. Aguiar, and J. Hierrezuelo, "The work of the frictional force in rolling motion," Phys. Educ. 28, 225-227 (July 1993), nonconservative forces need not be dissipative.C. Carnero and J. Aguiar and J.Hierrezuelo, " The Work of the ...

On the other hand, the work done by any nonconservative force, such as friction due to air, depends on the path followed and not alone on the initial and final positions, for the direction of such a force varies with the path, being at every point of the path tangential to it. See ...
2. Conservative and non-conservative forces A force is said to be conservative if work done by or against the force in moving a body depends only on the initial and final position of the body, and not on the natural path followed between the initial and final positions. If the work done...

is equal to the work done by the forces acting on the particle. These forces can either be conservative or non conservative. The force F(t) is the resultant of these forces. If gravity is acting on the particle, the work done by gravity is given by Where: ...
