Physics of Dunking!



One of my favorite thing to do in basketball is dunking. I dunk at least 4 to 5 times a game and now that I am in physics I can show that physics is in dunking. First thing is that you jump into the air with an acceleration of -9.81 because that is the opposite of gravity. At my highest point which is about 3.5 meters high I have a velocity of 0 because for a short time I stop and I am not moving at all. My kinetic energy at the top equals the potential energy at the bottom. During dunking I do work on the ball. The ball's force is 624 grams * 9.81 m/s^2 which equals 6,121 newtons. I lift the ball 2 meters high when you multiply 2 meters by 6,121 newtons you get 12,242 joules. The power on the ball is 6,121 watts because I lifted the ball in 2 seconds. I love basketball which has physics in it!!!!!!!!!!!!!!!!!!!!!!!!!!!!
