Rolling Friction: The resistance force of the body when it rolls on the surface.

Dynamic Friction: Is also known as kinetic friction, is a resistance of body between moving surface of moving body to steady surface of steady body.

Limiting Friction: The maximum force that can be used to start motion of the body.

Static Friction: The force required to keep body at rest.

Here, n case, if anybody experiences an external force resulting from its motion, it is said to have the dynamic (kinetic) motion.

While, if the body is in motion but not because of any external force, then it may be included in kinematics.

@Deepak Sharma & @Dinesh.

When a body is rolling on a surface it will be acted by a certain amount of friction between surface is called rolling friction.

When a body is in rest and the amount of friction it is acting towards the surface just before it is going to motion is called limiting friction.

Can you explain other options please, am clear now with dynamic friction.

What is limiting friction?

Deepak Chobey said:   10 years ago
The body move one motion other motion, in this motion the dynamic force is generated, Force is related to limiting friction convert to dynamic friction, It is maintain restricted force depend on energy.

The force that must be overcome to maintain steady motion of one body relative to another because they remain in contact.

What is dynamic friction?

SANTOSH said:   1 decade ago
The word dynamic refers to motion, static refers to rest position, rolling is one of the motion, limiting is just like fluctuations in motion.

How many types of friction are there?
