Question

For each of the following interactions, identify Newton’s 3rd law pair forces i.e. action and reaction forces.
a. A hammer hits a nail
b. Earth’s gravity pulls down on you.
c. A helicopter blade pushes air downward.
d. A wave hits a rocky shore.

Answer 1

Answer:

Newton's Third Law says that every interaction involves two forces - in this case (1) hammer pushes nail, and (2) nail pushes hammer. When a hammer hits a nail, Newton's Third Law says that the force that the hammer exerts on the nail is exactly the same size as the force the nail exerts on the hammer
