Vedclass · Answer

(C) force is called conservative if the work done by it in moving a particle between two points is independent of the path taken. Field forces,such as gravitational force and electrostatic force,are conservative because the work done by them depends only on the initial and final positions. Contact forces,such as friction and air resistance,are non-conservative because the work done by them depends on the path taken,and they often dissipate mechanical energy into heat. Therefore,field forces are generally conservative,and contact forces are generally non-conservative.

Out of contact force and field force,which force is conservative and which force is non-conservative?
