Basketball is not just a game of shooting baskets and getting points. It is a game that includes a lot of physics. In basketball, there is a lot more physics than most people would expect. The different principles and formulas in physics relate to basketball in many different ways.
One way physics relates to basketball is in the jump. Did you know that you do not spend equal amounts of time on the top and bottom half of your jump, as people usually believe? Instead, you spend about 71% of the time on the top half of your jump and 29% on the bottom. This is because of the speed you are moving at when you initially the off from the ground. Since you are moving the fastest when you leave the ground, your height increases as you jump, but the speed also decreases after you leave the ground. At the height of your jump, your speed is at zero, and then it increases again as you fall back to the ground. Since your speed is increasing as you jump up, and as you fall down, the longest part of your jump is when you are in the air at the top part of your jump.
Another way physics relates to basketball is in layups. In basketball, in order to make a layup you cannot throw the ball straight at the backboard and hope it bounces back into the hoop. In order for the ball to go in, you need to think about the physics behind it. As you are running towards the hoop for a layup, your speed is added to the speed of the basketball. As you release the ball from your hands, it continues to move forwards with your speed from running. If you push the ball towards the hoop it will bounce right back, but if you throw it up taking your speed into account, it is more likely that they ball will go in the hoop. This is all based on an experiment by scientist Galileo Galilei. He figured out that when an object is let go, it will travel with the speed from whatever had released it. This is why the basketball does not go straight up and fall straight back down, but moves forward after you release it.

Lastly, physics relates to basketball in each and every shot. A ball shot with more backspin is more likely to go into the hoop than a ball shot with no backspin. Why? Well, physics explains this. When a ball is shot with more backspin, once it hits the rim the energy decreases more than it does when a ball with no backspin hits the rim. This is why basketball players are taught to shoot with their fingertips instead of their palms. The fingertips provide more backspin on the basketball which makes it more likely for the ball to go in. When a ball with no backspin hits the rim, the hit causes some friction which takes away some energy and slows the ball down. But, when a ball with backspin hits the rim, the hit causes even more friction which allows even more energy to be taken away. This slows the ball down even more than the no backspin ball, leaving less energy and a greater chance for the ball to bounce into the basket instead of away from it.

Every aspect of basketball has at least some physics in it. Whether it is shooting, jumping, passing, or making layups, physics is a part of basketball. Without physics, some things in basketball may have no explanation at all.
