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.

    A higher velocity and acceleration will allow player #11 to get away from the blue defenders [Figure2]

  • In addition to speed, velocity and acceleration are important measures of a hockey player’s movements on the ice.

Can You Apply It?

With the links below, learn more about speed, velocity, and acceleration. Then answer the following questions.

  1. Velocity describes two things about a moving hockey player. What are they?
  2. 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?
  3. What happens when a hockey player accelerates?
  4. 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.
