Shooting
Shooting is a very exciting part of the game of
hockey. In order for players to score goals they must
not only have a hard shot but also a very accurate
one. The 2 most common types of shots in hockey are
the slap shot and the wrist shot. The slap shot is the
harder of the two but the drawback is less accuracy.
At the 2012 NHL
All Star Competition Zdeno Chara broke the record for
hardest slap shot with a shot of 108.8 mph which is 48.4
m/s. A puck weighs just .17 kg but with a shot at that
speed it would have a momentum of 8.2 N s. The
hardness of a frozen hockey puck offers very little impact
time which sounds painful for a goaltender! The
elasticity and flex of the stick is what allows these
players to shoot the puck at such high speeds. A few
students from Kettering University did research on the flex
ratings of hockey sticks and what each stiffness is in units
of N m.|
