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 what measurements are necessary to calculate the speed of a hockey puck sliding across ice. This involves understanding the type of data required, such as distance traveled and time taken, to determine the puck's speed.
Answer
Measure distance and time taken; use speed = distance / time.
To identify the speed of the puck, measure the distance traveled over a period of time and use the formula speed = distance / time.
Answer for screen readers
To identify the speed of the puck, measure the distance traveled over a period of time and use the formula speed = distance / time.
More Information
Speed is calculated by dividing the distance traveled by the time it takes to travel that distance. In ideal conditions (constant speed), this will give an accurate measurement.
Tips
Ensure accurate measurement of both distance and time intervals to minimize errors in the calculation. Check if the puck is moving at a constant speed.
