Jump Shot

Description: Ray Allen is shooting the ball towards the basket with a backspin, which allows the ball to slow down just enough to fall gently into the basket. The goal is to allow gravity to put the ball into the basket not the extra force exerted by your wrist. Since he is shooting it at a perfect angle the ball will not hit too hard off the rim and if he misses, the ball may still roll in due to it's reduced speed. By bending his legs he gives his body enough strength to push of the ground. He uses pressure from his legs to force himself off the floor. the amount of pressure he exerts allows him to have a greater upward force then the downward force of gravity. Using torque, Ray makes the ball have a lot of backspin, he has to grip the ball and flick it off his hand using his wrist. The ball will roll of his finger tips, creating enough friction to stop the ball from simply just going forward and it will make it spin backwards whe he launches the ball forward. His left hand asks as a guide hand which creates more friction, but it's main function is to keep the ball straight. Since the is more force in the torque of Ray Allen's wrist then the friction cause by his left hand, the ball will not stop spinning backward and it wont be pushed to the right.
