# Which force is non-conservative force?

## Which force is non-conservative force?

If the work done by a force depends not only on initial and final positions, but also on the path between them, the force is called a non-conservative force. Example: Friction force,Tension, normal force, and force applied by a person.

How frictional force is non-conservative?

A nonconservative force is one in which the work done in moving an object/particle is dependent upon the path taken. A conservative force is path-independent, and depends only on the position of an object. The force of friction, however, is path-dependent.

### Why is friction a non-conservative force Class 11?

Friction is an example of a non-conservative force. A force is said to be a non-conservative force if it results in the change of mechanical energy, which is nothing but the sum of potential and kinetic energy. The work done by a non-conservative force adds or removes mechanical energy.

What are non-conservative forces?

Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from the system as the system progresses, energy that you can’t get back. These forces are path dependent; therefore it matters where the object starts and stops.

#### What is the difference between conservative force and nonconservative force?

A nonconservative force is one in which the work done in moving an object/particle is dependent upon the path taken. A conservative force is path-independent, and depends only on the position of an object. The force of friction, however, is path-dependent.

What is the difference between a conservative and path independent force?

A conservative force is path-independent, and depends only on the position of an object. Gravity is an example of a conservative force. The force of friction, however, is path-dependent. For example, if we push an object 1m across a rough surface, less energy will be lost as heat than if we push that same object 5m across the same surface.

## What is the function of force friction?

Friction is a dissipative force that is path-dependent and resists relative motion between systems in contact. This type of force removes energy away from the system as the system progresses leading to mechanical energy not being conserved.

Are electromagnetic forces conservative in nature?

So in reality electromagnetic forces are not conservative, because they lose energy in the form of radiation. But, that shouldn’t affect friction, because most of the friction can be derived (atleast I think) from rigorous analysis of Coulombs force.
