1. Can an action force exist without a reaction force?

2. When a hammer exerts a force on a nail, how does this amount of force compare with that of the nail on the hammer?



Answer :

Final answer:

Newton's Third Law states that every action has an equal and opposite reaction in physics.


Explanation:

Newton's Third Law of Motion states that every action has an equal and opposite reaction. When a force is exerted by one object on another, the second object exerts an equal force in the opposite direction. In the case of a hammer hitting a nail, the force exerted by the hammer on the nail is equal in magnitude to the force exerted by the nail back on the hammer.
