Slap shots
The Question: What makes a slap shot in hockey so fast and accurate?


Most people think that the power of a slap shot comes from arm power. This is partially true. The power of a slap shot actually comes from the weight of your body and the speed at which you swing your stick.When you perform a slap shot you transfer the weight of your body and the power of your body to the stick. The stick will hit the ice a few inches behind the puck causing the stick to flex.

Hockey rinks are slippery. this is because they have a lot less friction then normal surfaces like carpet of concrete. this allows the puck to slide on the ice better.

When the stick gets to the puck all the momentum is transferred from the stick to the puck. With a final flick of the wrist the puck is sent in the intended direction. When doing a slapshot friction is one of the key things you need. Without friction you would not be able to do a slap shot. The tape on the hockey stick is also key. The tape on the stick makes it a roughfer surface, this causes more friction. Without the tape, the puck could slide off your blade causing the puck to go in the unintended direction.

Answer: The power from a slap shot comes from a combination of arm power, the speed at which you swing your stick, and your body weight. all the momentum from your body is transfered through the hockey stick which intern flexes causing the puck to flick off your stick.
