Speed in Hockey:
Speed is very important in hockey because the faster you can get down the ice to score, the
less chance the opposite team is going to be able to keep up.
Velocity in Hockey:
Velocity is also very important. If your speed and direction are just right, you may
get that one big check you have been waiting for. Or you may get that goal that you have always thought impossible.
Acceleration in Hockey:
Acceleration in hockey is an important factor if you want to out skate the other team.
The faster you get up to top speed, the better chance you will get the puck before the other team. Acceleration is also
important when you get a breakaway and want to score so you can out skate the other 2 or 3 players defending the goal.
Momentum in Hockey:
In hockey momentum is essential in checking other players. Players use their body and
speed to get the opposite team off of the puck.
Common forces:
Air resistance:
Players are affected by air resistance when they are moving. The air pushes against
them slowing them down. This is also true for the puck. When it is moving, air slows it down.
Gravity:
Gravity keeps the puck and the players on the ice. When the puck is in the air, gravity is
what brings it back down.
Sliding Friction:
The puck has sliding friction because it slides on the ice when a player hits it with his
stick or his skate. A players skates have sliding friction because they also slide on the ice. When the blade puts pressure
on the ice, it creates a cushion of water that helps the blades move along the ice.
Static Friction:
A puck has static friction when it is not moving. A player also has static friction when he
is not moving. Static friction is the bonding between two bodies at rest.
Kinetic Friction:
Kinetic friction is the friction that tends to slow a body in motion. Kinetic friction helps
slow the puck down and also slow players down that are in motion.
