The physics of hockey (well some of it)
So back before I injured my knee I used to play hockey. I loved the sport and I was pretty good at it, nothing great but pretty good. I did however have quite the slap shot. At a camp they measured how fast using a speedometer. It clocked in at 86 miles per hour, which wasnâ€™t too shabby for being in 8th grade. Now letâ€™s find the acceleration of the puck.
Saying that the puck stays flat on the ice for the whole distance (20m) traveled and neglecting friction and saying it takes 3 seconds to reach the net we know:
Vf: 86 mph or 38.4 m/s
T: 3 s
We can use the equation:
The slap shot encompasses many parts of physics; the stick has potential energy as it flexes back as well as kinetic energy from being swung forward, the mass of the player helping accelerate the puck in a quicker time.
