Question

The puck is in the goal crease. A defending player, lying on the ice outside of the crease, places their hand on the puck and pulls it out of the crease and into their body, thereby causing a stoppage of play. Does this situation call for a penalty shot?

Answer 1

In ice hockey, deliberately covering the puck in the goal crease usually results in a penalty shot. From a physics standpoint, a hockey puck's motion is governed by external forces, such as those from a player's stick or friction with the ice.

Step-by-step explanation:

The question you've asked pertains to a situation in ice hockey, where a defending player lying on the ice outside of the goal crease pulls the puck into their body, causing a stoppage of play. In the official rules of ice hockey, this action would typically result in a penalty shot if the defending player deliberately covers the puck in the goal crease. This rule is intended to prevent players from stopping a play unlawfully and giving their team an unfair advantage.

As for the conceptual physics part of your query, a puck's motion on ice can be explained by the laws of physics. For example, Figure 5.7 demonstrates that a puck at rest will remain at rest until acted upon by an outside force, such as a hockey stick, and a puck in motion will continue on its path until another force, like friction from the ice surface, causes it to slow down.
