Question

what are contacts and non contact force? give two example of each.​

Answer 1

Answer:

NON-CONTACT FORCES: These are forces that act between two bodies that does not require physical contact between the bodies. a. Gravitational force: It is the force which attracts any two objects with a mass.

A contact force is any force that requires contact to occur. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball across a room are some of the everyday examples where contact forces are at work.

Answer 2

Contact Force

• The force which acts only when an objects are in physical contact with each other.
• Forces that act only when there is physical contact between two interacting objects are known as contact force.
• Examples: Muscular Force and frictional Force

Non - Contact Force

• The force of interaction which acts on an object without it's having any direct physical contact with another body.
• Example: Gravitational Force, Magnetic Force and electrostatics Force.
