PRINCIPLES OF MECHANICS IN SLAP SHOT IN ICE HOCKEY1)

  • Ice hockey, as the only ball team sport in the Winter Olympics, exhibits the perfect combination of skill, strength and speed, and reflects the olympic spirit of "Faster, Higher, Stronger - Together". From the perspective of mechanics, we analyze and discuss the important factors in slap shot in ice hockey, and reveal the underlying mechanics principles. By designing model experiments for slap shot in ice hockey, it is found that the angular velocity and the length of the stick have important effects on the speed of the puck. From the law of conservation of angular momentum and conservation of energy, it is found that the speed of the puck is proportional to the angular velocity before the player hits the ball, and the speed of the puck increases after hitting as the distance from the puck to the axis of rotation increases.
