Question

Can force be applied without an interaction between the objects? Explain with example.

Answer 1

Yes, non contact force are experienced on one body by other body without any actual contact between the bodies.


Gravity as well as electrostatic and magnetic attraction and repulsion provide real life examples of forces being exerted by one object on another without them being in contact with each other. Many children are aware of magnetism and have played with fridge magnets. They may also have played with picking up small pieces of paper or other objects with a comb charged by rubbing against the sleeve of a jumper or by pulling through hair. They will also be aware that things fall towards the Earth. However, they are unlikely to think about these experiences as involving forces, i.e. pushes and pulls.

It is common for students to think that all metals are attracted by magnets, and that the size of magnets determines their strength

magnetic force also attracts or repels other magnets without any physical contact, so the answer is yes.

An interaction of one object with another object results in a force between the two objects .

In other words, A force will arise due to interaction between two objects.If there is no interaction between two objects , no force can show it's effect.

At least two objects must interact for a force to come into play. Thus, an interaction of one object with another object results in a force between the two objects and no physical contact is necessary.
