Question

List the advantages of friction.

Answer 1

Frictional Force:

1. Friction is a resistive force that opposes the motion of a body.
2. It occurs at the surface that is in contact with the moving object.
3. This phenomenon occurs according to Newton's third law of motion which states that every action has an equal and opposite reaction.

Advantages of Friction:

1. It is a necessary phenomenon as it helps to stop a moving body.
2. It also helps in reducing the velocity of a fast-moving body
3. It helps us keep our balance between our legs and the ground on a slippery surface.
4. It can be used for the purpose of converting one form of energy into another.
5. A nail or a sharp object can be driven into a wall.
