what are contact and non contact forces? give two examples of each
Answers
We already know the basics of force and its type,i.e. contact force and non-contact force. In this article we are going to talk about the concepts of Non-Contact force and examples of non-contact force.
What is Non-Contact Force?
When you jump, you always return back to the surface. Why? Is there anything that is holding your feet when you try to jump? When you throw a ball high up in the air, it reaches the highest point and then it invariably return back to its thrower on the ground. These occurrences can be explained by the non-contact force. A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction. When compared to the types of contact forces, there are very few non-contact forces.
Non-Contact Forces Types
Gravitational Force
Gravitational force is responsible for bringing the items we toss into the air back to earth. When an object is resting on a surface it is exerting a downward force equal to its weight and this downward force is known as Gravitational force.
Answer:
Contact forces Non-contact force
There is no field linked with the contact force. There is always field linked
with non-contact force.
Friction is an example of contact force. Gravitational force is an example of
non-contact force.
