Newton's Laws of Motion — Quiz

Question 5 • Physical Science

How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?

Answer
A
Smooth ice decreases the reaction force that the ice exerts on the hockey puck.
B
Smooth ice increases the force used to accelerate the hockey puck.
C
Smooth ice reduces the inertia of the hockey puck.
D
Smooth ice reduces the unbalanced forces that would slow the hockey puck.

Explanation

By Newton’s first law, a moving puck keeps moving at a constant velocity unless an unbalanced force acts on it. Smooth ice reduces friction, so there is less force opposing the puck’s motion and slowing it down; this lets players pass it more quickly. Smooth ice does not reduce the puck’s inertia, which depends on its mass.
