A hammer drives a nail into a piece of wood. Identify an action-reaction pair, and compare the forces exerted by each object.

Question

a
The hammer exerts a force on the nail; the nail exerts a force on the hammer.
b
The hammer exerts a force on the nail; the hammer exerts a force on the wood.
c
The nail exerts a force on the hammer; the hammer exerts a force on the wood.
d
The hammer exerts a force on the nail; the wood exerts a force on the nail.
Question 30 (1 point)
A hockey stick hits a puck on the ice. Identify an action-reaction pair, and compare the forces exerted by each object.
a
The stick exerts a force on the ice; the ice exerts a force on the puck.
b
The stick exerts a force on the puck; the puck exerts a force on the stick.
c
The puck exerts a force on the stick; the stick exerts a force on the ice.
d
The stick exerts a force on the puck; the puck exerts a force on the ice.

Answer 1

For both questions, we can identify the correct action-reaction pairs based on Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.

For Question 29 (Hammer and Nail):

The correct answer is: a The hammer exerts a force on the nail; the nail exerts a force on the hammer.

Comparison of Forces: The force exerted by the hammer on the nail and the force exerted by the nail on the hammer are equal in magnitude but opposite in direction.

For Question 30 (Hockey Stick and Puck):

The correct answer is: b The stick exerts a force on the puck; the puck exerts a force on the stick.

Comparison of Forces: The force exerted by the hockey stick on the puck and the force exerted by the puck on the hockey stick are also equal in magnitude but opposite in direction.

In both scenarios, the forces involved are part of an action-reaction pair, demonstrating Newton's Third Law.
