Question

what is meant by saying that force is due to an interaction? give an example to illustrate your answer​

Answer 1

whenever we see a force acting we see actually two bodies exerting force on eachother. As per third law forces apply in pairs always.

so actually whenever we note a force there are actually two forces and two bodies interacting mutually.

I can say I was singing but there was no one present around so no one listened to my sound.

but

there is no example where we can say a body had applied force but there was no other body around hence no body felt it .

so in short ...

Application of force is not a single body phenomenon but at least there must be two bodies to interact.

Answer 2

Answer:

Interaction is only possible if two objects are working together, such that one is affecting another. whenever we see a force acting, we see two bodies exerting force on each other. If one is applying force then other is either accepting it or opposing it depending on the situation, so the statement is justified that force is always due to interaction.

Explanation:

A man kicks a ball, and ball start moving, here a man is applying force and interacting with a ball which in response started moving. Hence statement is justified.
