Question

The frictional force is an example of conservative force.

• A. True
• B. False

Answer 1

The correct option is B False

Conservative force

1. A conservative force is a force where the work done in moving a particle from one point to another is independent of the path taken by the particle.
2. It depends only on the initial and final position of the particle.
3. Example: gravitational force, elastic spring force.

Non-conservative force

1. A non-conservative force is one for which work depends on the path.
2. Example: frictional force

Friction is non-conservative because the amount of work done by friction depends on the path.

Therefore, the given statement is false.
