what is non contact force
Asked by tronak75439 | 19th Feb, 2020, 09:53: PM
Expert Answer:
Forces which come into play when two objects do not have any physical contact between them are called non-contact forces. The most familiar example of non-contact force is weight, which is the force exerted on an object in gravitational field due to earth or any other planet or any celestial object like moon.
Other examples for non-contact forces are :- magnetic force, electrostatic force.

- How can we say that force is an interaction between 2 objects if non contact force is also there?
- What do we call such forces that do not require any physical contact with the object on which they act? Give two examples of such forces.
