When a skater glides across the ice on only one skate, what kind of motion does the skate have? Use principles of physics as evidence for your answer.
Why do baseball players often slide into second base and third base, but almost never slide into first base after hitting the ball? (The answer depends on both the rules of baseball and the laws of physics.)
Describe the motion of a hockey puck between the instant the puck leaves a player’s stick and the instant it hits something. (No “slap shot” allowed; the puck must remain in contact with the ice.)
