In a Flash!
This pro ice hockey player is racing over the ice. He whizzes by the spectators in a flash. Hockey is one of the fastest of all sports. A professional hockey player may reach skating speeds of close to 30 miles per hour!
Why It Matters
- Fast skaters have a big advantage in hockey. Speed allows them to duck into spaces between other players and escape the other team’s defense.
- In addition to speed, velocity and acceleration are important measures of a hockey player’s movements on the ice.
To see how these measures apply to ice hockey and how they are calculated, watch this video: http://www.nbclearn.com/nhl/cuecard/56612
Can You Apply It?
With the links below, learn more about speed, velocity, and acceleration. Then answer the following questions.
- Velocity describes two things about a moving hockey player. What are they?
- Assume that a hockey player skates 60 feet in 3 seconds. What is the player’s speed? If the hockey player travels this distance from East to West, what is his velocity?
- What happens when a hockey player accelerates?
- Assume a hockey player accelerates from 0 ft/s to 24 ft/s over a period of 2 seconds. What is his acceleration if his direction does not change? Explain in words what this acceleration means.
