His name is Slapshot, and he’s the mascot of a hockey team. He’s named for the fastest moving object in any team sport. When a hockey player makes a slapshot, the puck may reach a speed greater than 100 miles an hour!
The Back Story
- How can a hockey player cause the puck to move so fast? It takes a lot of skill. A slapshot is arguably the hardest shot to make in hockey. A skillful hockey player may not know it, but a slapshot also involves a lot of science.
- The slapshot is a good example of how work, energy, and power are related in physics. Watch this video to see how to make a slapshot and why it is so powerful: http://www.nbclearn.com/nhl/cuecard/56603
Can You Apply It?
With the link below, learn more about slapshots. Then answer the following questions.
- Briefly describe how a slapshot is made. Identify sources of kinetic and potential energy in the shot.
- When energy is transferred from the hockey stick, only some of the energy goes to the puck. What happens to the rest of the energy?
- What is the physics definition of work? How is work calculated? How would you calculate the amount of work done in a slapshot?
- What is the physics definition of power? How would you calculate the power of a slapshot? Why is the power of the slapshot so great?
- Slapshots are very fast, but there are trade-offs for all that power. What are two drawbacks of slapshots?
