A hockey puck slides across frictionless ice at a constant velocity. Which of Newton's Laws best explains this?
A hockey puck slides across frictionless ice at a constant velocity. Which of Newton's Laws best explains this?
- Newton's Law of Gravitation: Explains the attraction between the puck and the Earth.
- Newton's Second Law: $F = ma$ implies constant velocity requires constant force.
- Newton's Third Law: The puck's motion produces an equal and opposite reaction.
- Newton's First Law: An object in motion stays in motion unless acted upon by a force. (correct)
