A hockey puck glides far on an air table because friction is nearly gone. This illustrates Newton's:
AThird law
BGravity law
CFirst law
DSecond law
Answer & Solution
Correct answer: C. First law
1. With the air off, friction stops the puck quickly.
2. With friction gone, motion continues at constant velocity.
3. That is the first law, the law of inertia.
