PHYSICS BEHIND ICE HOCKEY
64
- 6 players per team
- One is a goalie
- Begins when two players face off
- Puck into net equals one point
- When the puck sits on the ice waiting to be hit, it has gravitational potential energy.
- After the puck is hit by the hockey player the potential energy is converted into kinetic and thermal energy. ( The thermal energy comes from the friction of the ice and the puck)
- After the player makes a goal or misses the kinetic energy is turned back into potential energy.
PHYSICS BEHIND ICE HOCKEY
By Akhil Sadhu and Jinha Choi
HISTORY OF ICE HOCKEY
- Began in Novia Scotia, Canada.
- Began close to the 1800’s
- Inspired by the British Field hockey and a game played by the indigenous groups in canada.

ABOUT THE SPORT
HOCKEY
EQUIPMENT
- ACCELERATION
- Velocity
The puck accelerates when the puck is in constant motion sliding on the ice, but it changes in acceleration when the force from the hockey stick to the puck.
BASIC SETUP
The hockey players have a constant velocity until it is acted on by the unbalanced force such as the wall or other players.
- Sticks
- Skates
- Safety pads
- Helmets
- Puck
- Ice Rink
- Goal
- Friction
In hockey friction is created in two main ways the skates: rubbing against the ice, and the puck sliding on the ice.

Three Main Rules of Hockey
- Off sides: when any member of the attacking team precedes over the defending team’s blue line.
- Offside pass: when a player passes the puck from his defending zone to a teammate beyond the red center line
- Icing: when a player shoots the puck across the center redline and past the opposing red goal line.

NEWTONS LAWS
- 1ST LAW
The object at rest stays at rest unless unbalanced force is added. the object in motion stays in motion unless unbalanced force is added.
The puck stays at rest until the hockey players give an unbalanced force into the puck.
the puck stays in motion flying until it has reached the goalie or the player that received the puck.
THE ENERGY
- 2ND LAW
F = MA
A goalie with heavier gears on need more force to accelerate.
- 3RD LAW
All forces act as pairs
When hockey players collide with each other, the smaller
player would pushed backwards because of the force acted on by the other players.
