What is the contact force and non contact force?what is non contact force
Answers
Answer:
Contact & Non-contact forces
External force comes into picture when the body starts moving or comes to rest either by coming in contact with the body or without being in contact.
Contact force-
force applied by coming in contact with the body
Example:
- hitting of cricket ball with bat in game
Non-contact force-
force applied without coming in contact with body.
Example:
- coin attracted towards magnet(magnetic force)
- ball dropped at height attracted towards the earth (gravitational force)
Answer- The above question is from the chapter 'Force and Pressure'.
Force is a push or a pull.
Contact force: The force which occurs when two or more bodies are in contact with each other is called contact force.
For example: Muscular force, friction, etc. are contact forces.
Illustrations:
An ox is pulling a cart. (Muscular force)
We are able to move on the road. (Friction)
Non-contact forces: The force which occurs when two or more bodies are not in contact with each other is called non-contact force.
For example: Magnetic force, gravitational force, electrostatic force, etc.
Illustrations:
Magnet attracts iron. (Magnetic force)
An apple always fall down on the ground. (Gravitational force)
A comb when rubbed with dry hair attracts small bits of pieces of paper. (Electrostatic force)
