What happens to the kinetic energy of a hockey stick?
What happens to the kinetic energy of a hockey stick?
The result is the puck reaching a speed faster than it would if the player simply hit the puck directly. The kinetic energy of the puck after impact is equal to the stored energy in the hockey stick. The figure below shows the point of impact between the stick and puck. You can clearly see the bend in the stick.
How does a hockey player swing their stick?
The player will then swing their stick, striking the ice about 3-5 inches behind the puck. The impact will flex the stick far enough (as seen in picture).As the follow through continues, less weight is exerted on the stick allowing the puck to release like a spring once the stick comes in contact with the puck.
What happens when a hockey stick comes in contact with the puck?
This caused the stick to “bow” considerably. When the stick did come in contact with the puck, the “bow” was released, snapping the stick towards the puck just as Friesen was following through with his swing (and transfering his weight). The overall motion is combined with the stick snapping back, releasing energy into the puck.
What is the force needed to bend a hockey stick?
In that case, a force F = 100 N will bend the stick through a distance x = 0.1 m and a force F = 200 N will bend the stick through a distance x = 0.2 m. If a puck is placed on the end of the stick in Fig. 1 and the force is suddenly released, the puck will shoot up in the air.
The result is the puck reaching a speed faster than it would if the player simply hit the puck directly. The kinetic energy of the puck after impact is equal to the stored energy in the hockey stick. The figure below shows the point of impact between the stick and puck. You can clearly see the bend in the stick.
How does the curvature of a hockey stick affect the puck?
One of the key features of a hockey stick that affects puck control is the curvature of the blade, which acts as a type of self-centering mechanism. When the puck is struck the curvature of the blade “forces” it towards the bottom of the curve, where it tends to sit for the brief duration of impact before flying off.
The player will then swing their stick, striking the ice about 3-5 inches behind the puck. The impact will flex the stick far enough (as seen in picture).As the follow through continues, less weight is exerted on the stick allowing the puck to release like a spring once the stick comes in contact with the puck.
