When two bodies are moving in different directions an letter tend to come close or slide toward each other, it means there is a frictional force between them. Since the two Bodies are motion is dynamic friction.

The friction has two types:

1. Dynamic friction.
2. Sliding friction.

Dynamic friction applied on the body in motion.
Sliding friction applied on the body in rest.

Dynamic implies motion.

When body is in motion then always act dynamic friction opposite direction to the motion.

Kinetic friction is the opposing force that comes into play when one body is actually moving over the surface of another body.

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.

Dynamics means motion.

Harish yadav said:   1 decade ago
How many types of friction are there?

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.
