Question

Differentiate between contact and non-contact forces (in points)

Answer 1

1.Non contact force is a force which on an object without coming physically in contact with.
2.The most familiar example of a non contact force is weight.
3.All four interactions are non contact forces.
Contact force
1. A contact force is a force applied to a body by another body.
2. Examples of contact forces are - Biological force, muscular force
3. Thus a contact force is a force that requires contact to occur.

Answer 2

Answer:

The interaction of two separate objects produces contact force. There is no touch between the two items as a result of the non-contact force, which might be either attraction or repulsion.

Explanation:

• Any force that develops as a result of two objects coming into touch with one another is referred to as a contact force.
• The majority of the observable interactions between macroscopic groupings of matter are caused by contact forces, which are pervasive.
• Contact forces include, for instance:
• Force of reaction. The reaction force is applied to an object that is at rest on a surface.
• Tension. When an object is stretched, a tension force is present.
• Friction. Friction forces exist between two things that are sliding past one another.
• Air pressure.
• A force that affects an object without making direct physical touch with it is known as a non-contact force.
• The most well-known non-contact force is weight-giving gravity.
• A contact force, on the other hand, is a force that operates on an object when it comes into physical touch with it.

Contact force is the result of two different things interacting. The non-contact force, which could be either attraction or repulsion, prevents the two objects from coming into contact.
