Shooting the puck in hockey has the most
physics. There are lots of transfer of energy, friction energy,
and using the flex of the stick. Flex is a measurement of how
strong the stick is. It determinds how much force can be pressed
down before the stick breaks. Higher the flex, higher pressure it
can handle. In this year NHL all stars event, Zdneo Chara had the
fastest slap shot in NHL, with the record of 105.9 MPH. Its
amazing how fast they can shoot the puck. There are lots of
physics behind getting the puck as fast as 105.9 MPH.
Most of the power comes from bending of the stick. As a player
gets ready for a slap shot, they swing back to get as much momentum as
they can when hitting the ice. As they swing foward, the weight
of the player transfers from back leg to the front leg and also the
stick. As the weight pushes the stick down, it uses the flex of
the stick. With the release of the bend, and the foward momentum
of the stick, when it hits the puck, the energy and the momentum is
transferred into the puck, making the puck move as fast as it
does. There are also friction of the stick when the blade of the
stick makes contact with the ice.
