Question

what is the effect of non contact force

Answer 1

Non Contact Force can be defined as:

Forces which come into play when two object do not have any physical contact between them.

or

When a force is applied on some body by another object without any interaction or contact is called non contact force.

or

In a Non-contact force the force information is transmitted over distance.

Examples of Non-Contact Forces are :

Gravitational force

Magnetic force

Electrostatics

Nuclear force

It differs from the contact force in the sense that physical contact is not involved here.

it is interesting to note that origin of all contact forces can be traced to non-contact forces.

Answer 2

the postion and motion of the object is changed

these forces come into action whn the two objects are not in physical contact.

These are - Gravitation,Magnetic and electrostatic forces
