Summary of Hockey

• How it is played Hockey is a game played on an
  ice rink in which two opposing teams of skaters,

• eastern Canada.
• First National Hockey League team

Newtons 1st Law in Hockey

• Newtons 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.
• Newtons 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 goalies glove, someone elses stick, or the
  net.

Newtons 2nd Law in Hockey

• Newtons 2nd Law states The acceleration of an
  object is equal to the force exerted upon it,
  divided by that objects mass.
• Newtons 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.

Newtons 3rd Law in Hockey

• Newtons 3rd Law states Every action (force) has
  an equal and opposite reaction.
• Newtons 3rd Law in Hockey When player 1 punches
  player 2 in the face, player 2s 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..
