In lacrosse there are many physics involved. These physics are important because they control how the game works practically. Some of these states of physics are only found in certain sports. For example lacrosse is one of the few sports thats has both centripetal force and projectile motion. Some of the physics that apply are listed below:
Newton's 1st Law of Motion-When one player acts upon another one may have more inertia forcing the other to fall.
Newton's 2nd Law of Motion-When using a stick to pass or throw the ball they use a push or pull motion causing the balls movement.
Newton's 3rd Law of Motion-When all their actions there is an equal and or opposite reaction. Like when the ball is coming at you for a pass, you can catch it or miss it.
Gravity-This determines how much force the player has to apply to the stick while passing the ball.
Air Resistance-This is exerted on the ball when it is in projectile also determining how hard they will pass the ball.
Friction- This force determines how long it will take to recover and how far the ball will roll on the ground while no one has posseion of it.
Centripetal Force-This occurs when the player cradles the ball because it's moving in a circular direction.
Speed, Velocity, Acceleration and Motion-
Inertia-The ball will stay still until hit or thrown.
Weight-The balls weight helps it move faster or slower depending on wether it's in the air or on the ground.
Momentum-When passing your swing momentum can help the ball pick up speed.
