4. Summary of Hockey
How it is played: Hockey is a game played on an ice rink in which two opposing teams of skaters, using curved sticks, trying to drive a small disc into or through the opposing goals.
Type of Equipment Used: (See photo)
Short history of sport’s beginning
and evolution: Starts in mid-1800s in
eastern Canada.
First National Hockey League team
in the USA was the Boston Bruins, in 1924.
Today, there are 30 teams in the U.S.

8. Newton’s 1st Law in Hockey
Newton’s 1st law states: An object at rest tends to stay at rest unless a force makes it move. An object in motion will stay in motion unless a force acts upon it.
Newton’s 1st Law in Hockey, an example: After a player hits the puck towards the goal, it will keep moving until it is stopped by the force of the goalie’s glove, someone else’s stick, or the net.

9. Newton’s 2nd Law in Hockey
Newton’s 2nd Law states: The acceleration of an object is equal to the force exerted upon it, divided by that object’s mass.
Newton’s 2nd Law in Hockey: A puck will change its speed quickly if a player slap-shots it (big force) because the mass of the puck is very small. If the player just bumps it with his stick as he is skating towards the goal, it will not accelerate quickly.

10. Newton’s 3rd Law in Hockey
Newton’s 3rd Law states: Every action (force) has an equal and opposite reaction.
Newton’s 3rd Law in Hockey: When player 1 punches player 2 in the face, player 2’s face also pushes back on his fist (so he feels that he landed the punch.) Also, when player 1 skates in at high speed to check player 2, player 2 exerts a force back on player 1, causing him to slow down or stop once they make contact. Also, when a player pushes down through his skates to skate quickly, the ice is pushing back up so that he can move forward…..
