Lacrosse Physics, illustrated introduction



PHYSICS of LACROSSE
An Introduction

Lacrosse player producing torque --
a turning force, just as you produce torque when hula hooping.

                      Your energy overcomes the force of gravity.

Trajectory of any ball:  forms the shape of an arc --
this is the trajectory of a ball in motion

Lacrosse ball at the end of its trajectory -- ready to be caught!

                      



SIMPLE MACHINES in LACROSSE:  LEVERS

Your arm works as a lever --

You have a longer lever when you hold a lacrosse stick.

In this picture the shovel acts as a lever, too -- 
just as a lacrosse stick is a lever.
