KEY ICONS TO LOOK FOR: Hockey players also need to maintain balance while accelerating over the ice surface. To do this, they typically lean forward in the direction of movement. This prevents them from tipping backward when the force generated by the forward movement pushes against them. Remembering Newton’s Third Law of Motion: for every action there is an equal and opposite reaction. Therefore, players need to counteract the forces working against them, such as torque (the rotational force caused by arm swing ) and gravity. Leaning forward moves the center of mass forward. Center of mass is the mean position of mass in an object. Keeping it forward allows for more forward momentum. Once a player has mastered the essential fundamentals of skating, the next hurdle is learning how to shoot. After all, you cannot win a hockey game if you do not score any goals.

R search Project: Hockey is just one of many sports that uses ice skates. However, the skates used in sports such as speed skating and figure skating are quite different. Do some research to create a cha t that compares and contra ts the differences in the skates. Be sure to include the scientific reasons behind these differences.
