Which among the following is a non-conservative force?

Answer: Frictional force is a non-conservative force.

There is no potential energy associated with non-conservative forces because it depends on the path between the starting and ending points. Friction creates thermal energy that dissipates, removing energy from the system. The work-Energy theorem is applicable to both conservative and non-conservative forces. The theory states that the net work on a system equals the change in its kinetic energy.

More information on Non-Conservative Forces

The details on non-conservative forces are as follow:

• They may be perceived as macroscopic effects of small-scale conservative forces.

• The non-conservative approximation for macroscopic systems is far easier to deal with than millions of degrees of freedom.

• They are also called dissipative forces because they dissipate mechanical energy into other forms.

• It converts macroscopic motion into microscopic motion.

• Frictional force, Viscosity, and air drag are examples of non-conservative forces.

Summary:

Which among the following is a non-conservative force?

Out of the given options, Frictional force is a non-conservative force.
