Question

what is the difference between contact force and force at a distance​

Answer 1

Answer:

Forces Different forces Contact forces involve push . Contact forces involve push, pull and friction. ... At a distance At a distance force is when two interacting force is when two interacting objects are not touching, for example: the moon and the Earth's seas. At a distance forces encompasses gravity and magnetism.

Answer 2

Answer:

CONTACT FORCES

• The force which occur when two bodies come in contact with each other is known as contact force.

• Example :- Frictional force, pushing a load etc.

FORCE AT A DISTANCE (NON-CONTACT FORCES)

• The force which occur when two bodies attract or repel against each other is known as non contact force or force at a distance.

• Example:- Magnetic force, Electrostatic force, gravitational force.

Explanation

$\rm CONTACT \ FORCE$

A footballer when kicks the football, applies his muscular force on his feet which enables his feet to touch and push the ball. Here, we can clearly say that there is a contact between the feet and the ball.

$\rm FORCE \ AT \ A \ DISTANCE$

Like poles of magnets repel each other at a distance before coming in contact or touch.

This shows that the magnetic force is present between the magnets without having a contact.
