Question

What is a non-conservative force? Give one
example.​

Answer 1

$\rule{200}{2}$

$\huge\boxed{\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}}$

A force that is not conservative is called a $\bf\large\underline\red{non-conservative\:force}$ . A non-conservative force is a dissipative force. The work done by a non-conservative force is lost and cannot be converted into useful work later.

$\bf\large\underline\red{Example:-}$ : A kinetic frictional force and force due to air resistance are non-conservative forces.

$\rule{200}{2}$

Answer 2

Answer:

1. Forces which depend upon the path taken
2. It has no relation with potential energy.
3. When the starting and end point are same, the total work done is not necessarily zero.
4. work done is not reversible.

eg air resistance
