When determining the motion of a hockey puck sliding across ice, what measurements would be needed to identify the speed of the puck?
Understand the Problem
The question is asking for the specific measurements required to determine the speed of a hockey puck sliding across ice, likely involving concepts from physics related to motion.
Answer
Measure time and distance or initial speed.
Measurements needed include the initial speed or the time and distance over which the puck moves.
Answer for screen readers
Measurements needed include the initial speed or the time and distance over which the puck moves.
More Information
To determine the speed of a hockey puck on ice, you often measure the time and distance over which it travels. If friction is negligible, the speed can be assumed constant.
Tips
Ignoring friction might be a mistake unless friction is specifically negligible.
