What is a force pair?

Answer 1

Force pairs act on the two different bodies. They can never act on the same body. For example, our a ball exerts a force [action] on the wall when it hits it. The wall exerts an equal but opposite force on the ball [reaction], so the ball bounces back.

Answer 2

All forces occur in pairs, because a force is an interaction between two things. An interaction, by definition, requires two things to be affected. This is Newton's third law.

I can't touch you without you touching me.

I can't poke you in the eye without your eye poking my finger

The sun pulls on the earth exactly as hard as the earth pulls on the sun.

However, while the forces are the same, the RESULT of those forces can be entirely different! This is because the MASSES of the objects might be different.

If F = ma, then you can have two equal F's with very different resulting a's. All depends on the masses.

Answer 3

A force pair is a pair of equal and opposite forces acting on two interacting objects. According to Newton's third law of motion, every action has an equal and opposite reaction, so when one object exerts a force on another, the second object exerts an equal force in the opposite direction on the first object.

Answer 4

Couple because couple is a pair of equal parallel forces that are opposite in direction.

Answer 5

All forces do.

Answer 6

In pairs
