Question

Difference between contact and non contact force​

Answer 1

Answer:

• Contact forces take effect immediately after the force is applied whereas there is a time gap between the application and the effect of non-contact forces.

• Contact forces can be represented by vectors. Non-contact forces can be represented by vector fields.

• There is always a field associated with a non-contact force, but there are no fields associated with a non-contact force.

Answer 2

Answer:

The force which acts from a distance is called non contact force

For ex - Gravitational and electrostatic force.

The force which acts when two objects are in contact is called contact force.

for example - friction force.
