Conservative force definition

The force which allows the opportunity of two way conversion among potential and kinetic energies is said to be conservative force.

Conservative forces examples

  • Gravitational forces
  • Magnetic force
  • Electrostatic force
  • Elastic spring force
  • Electric force

Non conservative force definition

The force is called non conservative if work is done by the force is dependent on path followed by body.oR The forces which are not conservative are called non conservative forces.

non conservative forces examples

  • Frictional forces
  • Viscous forces
  • Induction forces
  • Air resistance force
  • Tension in a string
  • Normal force
  • Propulsion force of the rocket
  • Proppulsion force of the boat

Difference between conservative and non conservative forces in tabular form

 Conservative forces  Non conservative forces
The force is called conservative if work done by force is dependent only initial and final position of body not depend on path followed by body. The force is called non conservative force if work is done by the force is depend on path followed by body.
    The work done by conservative force in close path is zero.        The work done by non conservative force in a close path is not zero.
