One of the most important elements of basketball is shooting. By learning how physics relates to basketball, athletes can improve their game.
Kinematics
Kinematics in shooting is extremely important if you want to be a successful shooter. To shoot, you must know how the parabolic arch can take you from an average shooter, to a great shooter. In my calculations, I calculated the acceleration and projectile motion.

Forces
Forces of shooting a basketball include:
- Normal Force (perpendicular to force of gravity)
- Force of gravity (insures ball comes back down)
- Force applied (insures the ball gets to the basket)
- Force of friction (when ball leaves hand)
- Force of tension (when the ball enters the mesh, force of tension slows the ball down)

Newtons Law's of Motion:
Newtons first law states that an object at rest, wants to stay at rest unless and unbalanced force acts upon it. In my video, you see a player shoot, it seems like there is nothing to obstruct the ball but several forces act upon it. If it weren't for these forces, the ball would continue to travel in its current direction. Firstly, a force of gravity acts upon the ball, causing the ball to be pulled down to earth. This causes the ball to make a parabolic shape. The athlete must judge the force of gravity by the weight of the ball to find the right line of trajectory. In my calculations, I have shown the FN, FG and FA with a free body diagram.

Newtons second law can be seen by the equation F = ma. Acceleration and force can be seen as vectors, meaning in this law the direction of the force vector is the same as the direction of the acceleration vector. It also means that acceleration and force are proportional to each other, the more force acted on an object, the faster acceleration there is. In basketball, while shooting this law applies because the more force you put on the ball, the faster it accelerates, the quicker it gets to the basket.
Newtons third law states that with every action, there is an equal and opposite reaction. This relates to basketball because when you release the ball from your hands while shooting, the force applied reacts back on your hand with the same amount of force.
In the calculations above, i was able to find all the forces on a basketball shot. These calculations are different from normal calculations while finding the forces because it has a angle at which the ball was released. This angle affects all of the forces. This is seen in the picture above.
Energy & Society
While calculating energy, I am able to see how much work and power is needed to complete a shot, 15 feet away from the net. As a basketball player, it is important to understand that work is the change in energy that basketball is performing, and power is that rate at which the basketball is doing work. In my calculations, I have shown the amount of work and power needed.
To calculate the work needed for the shot, I know the equation is W=F(d). After I plugged the numbers in, I was able to find the the athlete needed 3.35J of work. After I found work, I was able to find power with the equation P=W/t. After solving for power, I was able to find that the athlete needed 1.36W of power.
In conclusion, the athlete needs 3.35J of energy, and 1.36W of power to complete a shot 4.56m away from the basket.

EP1 = ball released
EP2 = ball at max height
ETOT= as it goes through the hoop
In my energy diagram, I am able to see that as the player starts with potential energy. When she shoots, at max height she also has potential energy and as it goes through the basket, she has potential and kinetic energy.
First, i found max height. My max height was 0.625 meters when i put it into the equation. I had to add the max height, to the athletes height released, and then add it to her vertical height jump. The final max height is 3.0632m.
Next, to find kinetic energy, i needed to find resultant velocity final. After using the equation the square root of v3=2agh2-agh3, i found the resultant final velocity was 5.49m/s.
Next, I was able to find EP1, EP2, and ETOT. With these calculations, you can see how much potential and kinetic energy was applied and where it was applied.
