what r contact and non-contact forces
Answers
● A non-contact force is a force which acts on an object without coming physically in contact with it.
☆ E.g: Gravitational Force
● In contrast a contact force is a force applied to a body by another body that is in contact with it.
☆ E.g: Frictional Force
FORCE-:
IT IS A PULL OR PUSH.
CONTACT FORCE-:
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.Example:- 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.
NON- CONTACT FORCE-:
A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.
