Question

what are central and conservative forces?​

Answer 1

Central Forces:

A central force is a force (possibly negative) that points from the particle directly towards a fixed point in space, the center, and whose magnitude only depends on the distance of the object to the center.

E.g: Gravitational force, Coulomb force, etc.

Conservative Forces:

A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the taken path. Equivalently, if a particle travels in a closed loop, the net work done (the sum of the force acting along the path multiplied by the displacement) by a conservative force is zero.

E.g: Force in elastic spring, electrostatic force between two electric charges,etc.
