Lesson�5:�The�Ice�Hockey�Stick
Teacher’s Notes
A stationary puck requires the
application of a great amount of
effort (force) in order for it to move
from rest to high speed in a very short
period of time. A longer stick design
makes the head of the stick move
much faster than the player’s hands.
(Think about the radius of a circle.)
A longer hockey stick, however,
may make the control of the head
movement more difficult. Applying
the lever principle: With a longer
hockey stick, the load (the puck) will
be further away from the fulcrum and
it will therefore need more effort
(muscle power) to hit it. A shorter
stick will require less effort and its
movement is more easily controlled.
The trade-off is that the hitting head
will not move as quickly.
That is the designer’s dilemma - how
to make best use of the science.
