This website shows a picture of the angle in a free throw line. This is very important because free throw line is pretty hard to shoot because you can’t jump and if you jump that doesn’t count as a point so the way you do it is you need to have more power and force to reach the hoop.
This helps me because it’s important to know how hard is the free throw line and by doing that you need to have a greater angle to shoot.

This website shows what is the angle of your arm when you shoot. The more you are on the right angle the better your shooting becomes and even if you bend too. 45 degree is a greater angle because it go in a smooth shot when you shoot.
This helps me because angle is a big important thing to shoot the ball in the hoop. Angle have a great force to shoot and the more you are bending the better you shoot.

This website show the calculus of the gravity in basketball. How to shoot with gravity and with the force. It show the calculate of the distance gravity.
This helps me because the gravity is also big part of the basketball. The distance of the gravity is better because without gravity it’s going to be hard to shoot

This website shows the force of the angle. The speed the the shots you take and calculate the average. Shows to bend your legs so so can get more speed and angle. Also it’s even depends how tall are you because it’s affect the force of your height and if you are short you need a lot of force to shoot in the net.
This helps me because it’s important to use the force in order to shoot the ball and also important to bend your knees and jump then you take the shot. Even the height if you are short you should better be closer to the hoop and tall can be any where.
This website show the backspin of the ball to shoot the hoop, in the free throw line you need to shoot perfect in the hoop, the arm need to be an angle to shoot the hoop nice and easy. If someone do a backspin the ball can hit the rim or the backboard. The more angle the more hoops you can get in. There is a magic formula that tells about the backspin.
This helps me because in a free throw line you can shoot the hoop without any defense men and it important so your team can get point, by doing that you need math to see the meters and how can you do it. The backspin is very good for free throw because it 
shoot better and get more shots in. When you always shoot make sure you always hit the backboard because when you hit the backboard it lets the ball to force in the hoop.
