What is the formula for newton's third law?

Answer 1

There is not technically a formula for the Third Law of Motion. It is simply a concept that explains 'reactionary' forces that exist in our everyday life. Yet, symbolically, the Third Law of Motion can be depicted as:

Fa = -Fb

Force applied depicted as, Fa, is equal in magnitude but opposite in direction to Fb.

An example of this idea would be if a person punched a concrete wall. The reason he is hurt by punching a concrete wall is because the wall applies a force equal in magnitude (as his applied force) but opposite in direction on the person.

Answer 2

The third law basically says that if you slap a table and it does not break, there must be an equal force exerted from that table. Or if I push the wall and the wall does not move, the wall is exerting an equal force to remain at the position that it is at. There is no formula to calculate this.

Answer 3

Every action has an equal and opposite reaction. There are not any terms for Newton's third law. Maybe Fa = Fb.

Answer 4

Fa = -Fb
