Conservative Forces
	When a force is conservative, it does not care about the path it takes to get there. Forces are described as conservative if the work done across any closed path is zero. It's known as a conservative force if the work done by a force depends only on the initial and ending positions, not on the path between them. Additionally, it is a force that acts on a particle, such that the work done by this force in transporting this particle from one place to another is independent of the path taken. To put it another way, only the particle's starting and final positions influence the amount of work it accomplishes. The gravitational force and the elastic spring force are two examples of conservative forces.

Nonconservative Forces
	For a non-conservative force, the path taken determines how much work gets completed. A force depends on more than just its initial and final positions; the path it takes to get there is just as important. Also, In a closed path, the non-conservative force isn't zero. Moreover, it is a force that acts on a particle, the work done by this force in moving this particle from one point to another is dependent on the path that this particle chooses to take. To put it another way, the amount of work done is directly related to the path used. For example, friction is nonconservative because the work done by friction always occurs in the direction of travel and so relies on the length of the path followed.
