Question

friction depends on dash of surface in contact​

Answer 1

Answer:

Explanation:

ANSWER:

friction depends on relative force of surface in contact​

WHAT IS RELATIVE FORCE?

Generally it means the force which occurs when one surface is in contact with another surface in the same place or surrounding which gives either resistive or adhesive force is called relative force.

WHAT IS FRICTION?

The force which acts between two surfaces in contact and gives out resistive force is force of friction.

There are different types of frictional force like:

• Rolling Frictional Force
• Sliding frictional Force
• Static Friction
• Limiting friction
• Drag or fluid friction.

WHILE PUSHING A CAR IF STUCK,

the force acts when:-

• We are pushing, Static
• The car is not moving , Limiting
• We are able to give force and move, Sliding friction
• The wheels move, rolling friction
• When any streamlined body moves in fluid like air and water, Drag.
• EXAMPLE: Aero Plane moving in air , Drag friction is experienced

STREAMLINE:

A body created such a way that is slant at the front to overcome fluid friction.

The front part of Aero Plane and fishes are slant.
