What are conservative forces?
Those forces which allows the opportunity of two way conversion among potential and kinetic energies are said to be conservative forces.
examples conservative forces
- Gravitational forces
- Magnetic force
- Electrostatic force
- Elastic spring force
- Electric force
what are non conservative forces?
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.
examples non conservative forces
- 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
Comparison table of conservative vs non conservative forces
|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.|
