Question

How can you differnative
a contact force and a force at a distance​

Answer 1

Answer:

Contact forces require physical contact for the effect of the force to be made on an object. A few examples of contact forces are friction, tension, air resistance, etc. Non-contact forces do not require physical contact for the effect of the force to be made on an object. A few examples of non-contact forces are gravity, magnetic force, electrostatic force, etc.
