What is central force and conservative force? Also explain these and also about non- central force.

central force is that whose magnitude only depends on the distance of the body from the origin. For example Gravitational force

Conservative force: force is said to be conservative if the work done by it depends only on the final and initial position of the body. For example a body moving along a circular path.

Non conservative force is that in which the work done depends on the path taken by the body. For example frictional force is a non conservative force.
