Hockey is a fast paced sport full of physics. A prime example is the slap shot.
The slap shot is basically a large rotational force. The player is rotating his body and uses the stick as essentially an extension of his body. You can calculate the force by finding the impulse on the puck.

By simple physics equations, we can find out that his stick is rotation at 12.4 radians per second! That's pretty amazing
we also can find out that chara was able to bow his stick almost an inch. That creates a huge buildup of potential energy that snaps on the puck causing it to reach these high speeds!
