Newton's third law states that if an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.

Let:

A = Hammer

B = Nail

so:


F_(AB)=-F_(BA)

Therefore:

The hammer exerts a force on the nail; the nail exerts a force on the hammer.
