Question

Is friction a conservative force? Give reason.

Answer 1

Hint: In order to answer this question let us first understand about force. A force is a push or pull on an object that occurs as a result of the object's contact with another object. As two things collide, each is subjected to a force. When the interaction is over, the two objects are no longer aware of the force. Forces can only exist by interaction.

Complete step by step answer:
A non-conservative force is one whose performance is dependent on the direction taken.Friction is an example of a non-conservative force. If a force causes a shift in mechanical energy, which is equal to the amount of potential and kinetic energy, it is said to be non-conservative.

A non-conservative force's function adds or subtracts mechanical energy. Thermal energy is dissipated as work is performed by friction, for example. It is impossible to recover all of the energy that has been lost. Properties of Non-Conservative Forces:
-Since it is path dependent, it is also affected by the initial and final velocity.
-The cumulative work performed by a non-conservative force in any closed direction is not zero.
-A non-efforts conservative's are irreversible.

No, friction is not a conservative force. A conservative force is path-independent and only depends on the object's location. Since the amount of work done by friction is dependent on the direction, it is non-conservative.

Note:Since the energy is lost to the system and cannot be converted into useful work later, non-conservative forces have no potential energy associated with them. As a result, any potential energy has a conservative force associated with it.
