okay i am only going into geometry, 9th grade. so try to go easy on me. Well, i was playing basketball the other day (i am a nerd, not an athlete) i have the physical ability of an athlete, just not the skills specific to any sport. Like in basketball, i can dribble, pass, steal, protect, but i can’t shoot. i miss everytime. so i started to to actually calculate my shot. like with wind speed, W , power P, angle A and all that. is it possible? if so, what would be a simple general formula. not simple like x + y = make just as simple as possible. no actual basketball techniques i won’t get it.
Spin on the Ball
Spinning the ball when you shoot is not done to affect air resistance, or to make air resistance cause the ball’s path to curve, as is the case in baseball. Basketballs move too slowly for that to happen. Once the basketball leaves the shooter’s hand, it travels in an unchanging parabolic path. So what’s the purpose of backspin? Backspin on the ball is used to help it to bounce into the net when it hits the rim. It will usually hit something, unless the throw was very high. The backspin, after contact with the back rim or board, will result in a change in velocity opposite to the spin direction, changing an equal-angle rebound into a velocity more toward the net. This makes it more likely that the ball will go in.
Receiving a Pass:
The impact of a hard pass can be lessened, making it less likely the ball will knock the wind out of you, if it is caught into the body. The ball coming at you has momentum, m·v. By increasing the time over which you decelerate the ball, you lessen the force. In other words, since m·v = F·t, then F = (m·v) / t … increasing t causes F to get smaller. This is the same principle that makes an air bag in your car work. The time over which you decelerate is lengthened, resulting in a lower force. Of course, catching a ball into your chest has other benefits. It makes it less likely you’ll drop the ball, and harder for someone to grab.
Bouncing the Ball:
The more air pressure a basketball has inside it, the less its surface will bend or deform during a bounce, and the more its original energy will be stored in the compressed air inside. Air stores and returns energy more efficiently than the material that the ball is made from. If the ball is underinflated, some of its energy is wasted in deforming the ball as it bounces, and the ball will not rebound very high. For the most elastic collision possible between the ball and the floor, you want a highly pressurized ball. (But you knew that already, didn’t you! Now you know why!)
The material you bounce the ball on is also very important. Think about how high it would bounce on a carpeted floor. A soft floor material will flex when the ball hits it, and this will steal some of the ball’s energy. Clearly the harder the surface, the better.
Starting, Stopping, and Changing Direction:
A players’ shoes must have good traction, which is the same as saying that the coefficient of friction between the shoe and the floor must be high. Friction is the force that opposes the motion of two surfaces that are in contact. Every surface is rough, on the microscopic scale, and when two surfaces come in contact, the high points on each surface temporarily make contact. The opposing or attracting forces of the surface molecules cause a ‘frictional’ force.
A basketball player will also make use of static friction; a foot firmly planted, rather than slipping across the floor, will provide more friction when he has to stop or turn suddenly. This is because static friction (‘pushing off’) is greater than sliding friction (‘sliding’). It is also why shoes must have a good grip on the floor in any direction you push off from, and why some shoes are unsuitable for basketball … they may have lots of forward traction, but slip too easily when pushing sideways. It’s just like driving … spinning tires have less frictional force than non-spinning ones. ABS systems keep the tires from sliding, and maintain more friction.

I am not sure to be honest. Why not try to substitute the letters for values then see how the ball reacts then just use trial and error until you finally get the correct formula. It is probably simple mathematics

The more wind speed the less power and angle needed
The more power the less angle and wind speed needed
The more Angle the less wind speed and more power needed.
W = Wind
A = Angle
P = Power
M = Made basket
W – A – P = M
P – W – A = M
A – W + P = M
That’s all I could think of..

If you work this out let me know.
Basket high and distance is going to come in to play.
