what are contact forces explain with examples in the different types of contact forces
Answers
A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar example of a 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.There are four types There are four types of contact forces Normal force, applied forces Normal force, applied forces Normal force, applied force, tension force and spring force.Pushing a car up a hill or kicking a ball or pushing a desk across a room are some of the everyday examples where contact forces are at work. In the first case the force is continuously applied by the person on the car, while in the second case the force is delivered in a short impulse.Contact Forces Action-at-a-Distance Forces
Frictional Force Gravitational Force
Tension Force Electrical Force
Normal Force Magnetic Force
Air Resistance Force .
if you are satisfy with my ans then mark me as a brainlist.
if there is something wrong then kindly rectify it
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.EG:- 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.
