Lacrosse is a team sport that originated in the St. Lawrence Valley area, around 1546. It is played with a small rubber ball, a long stick with a sort of basket at the end, and padding (it is a contact sport). The objective of the game is to shoot the ball into the other team’s goal, using the stick to pass, cradle and shoot. At first, the game was played on a distance of even several miles, and anywhere between 100 and 100000 players in a single game. The teams are now composed of ten players each, 3 of them are offense, 3 defense, 3 midfielders, that can go anywhere on the field, and one goalie, which is the heart of the team.

e. the tendency of an object to resist any change in its state of rest or motion. Centripetal force is force that counters the centrifugal force and keeps the object from going out of the circular path.
As you see in the centrifugal force diagram, if Walter (little guy) let go of the thing he is spinning, the thing would fly out on the path that is drawn, because the centripetal force is gone, and the only thing left is the centrifugal force and the force of inertia.
This also applies to shooting and passing.
Shooting (also Passing)
When passing (or shooting), the “top” hand pushes the shaft, while the “bottom” hand pulls back on the shaft. This creates a lever with your arms and stick, where you top hand is the fulcrum. A player can increases the force of his shot by driving his foot into the ground (while running), because of the high amounts of friction, the player almost comes to a complete stop. The player uses his torso and hips to turn, thus converting the linear momentum of his run, into circular momentum. The world record for the fastest lacrosse shot was mad by lacrosse super-star Paul Rabil, which was measured at an amazing 111 mph (178.637 kph).
