Physics of Lacrosse



While i was at lacrosse i was wondering, how do players get the ball to move out of their stick so fast? After practice I decided to look further into my question. By applying different topics that i learned in physics class, i was able to find an answer. there are many factors involved in throwing a lacrosse ball, one of them being momentum.

when throwing a lacrosse ball, you pull on the bottom of the stick and push on the top end while stepping at the same time. the momentum from your arms pushing and pulling on the stick causes energy to build up and transfer to the head of the stick. the stepping motion also allows your body to build up momentum which gets the ball moving at a greater velocity.

Static and dynamic energy is also a big part of throwing a lacrosse ball. while the ball is just sitting in the stick, it has static energy, however, when you pull your arms, you create dynamic energy. the dynamic energy passes through your body and into the stick. the energy travels through the stick and into the ball causing the ball to release from the stick. the velocity on the ball depends on how much momentum and energy you can get behind the ball. by using your entire body, from legs to arms, you can get more energy and momentum behind the ball creating a greater velocity.

Wow this is helpful.  Ive always wondered myself since im not a lacrosse player but this really helps me understand more!
