Question

3.
Name three types of frictional forces with suitable examples.​

Answer 1

Answer:

Types Of Friction

Following are the friction types which depend on the types of motion:

1.Static Friction

2.Sliding Friction

3.Rolling Friction

Static Friction

Static friction is defined as the frictional force that acts between the surfaces when they are at rest with respect to each other.

The magnitude of the static force is equal in the opposite direction when a small amount of force is applied. When the force increases, at some point maximum static friction is reached.

Examples:

>Skiing against the snow

>Creating heat by rubbing both the hands together

>Table lamp resting on the table

Sliding Friction

Sliding friction is defined as the resistance that is created between any two objects when they are sliding against each other.

Following are the examples of sliding friction:

>Sliding of the block across the floor

>Two cards sliding against each other in a deck

Rolling Friction

Rolling friction is defined as the force which resists the motion of a ball or wheel and is the weakest types of friction.

Following are the examples of rolling friction:

>Rolling of the log on the ground

>Wheels of the moving vehicles
