Basketball and the Jump Shot

Regardless of their grade in high school physics, these shooters have made their living by putting a ball in a hoop from great distances. So what are these players doing that other players are not? Well first of all, like anything shooting takes a lot of practice! But there are ways to maximize your shooting percentage using physics. In general, the physics of the jump shot revolves around projectile motion and kinematics.

__ ____F=MA__

Let's assume a shooter has stopped on the three point line and is about to take the a shot. What does F=MA (Newton's second law) have to do with this? All of the forces that are acting on the ball and the ball's constant mass are what determine how fast that ball is going to travel. This seems fairly intuitive, but many shooters aren't sure where all these forces are coming from. The force acting on the ball is the culmination of the shooters legs from the jump, his arms from shot, and his wrist from the release.

__Projectile Kinematics__

__Angle of release__

We can find out the
acceleration of the shot, and we can use
the kinematic equations to tell us many
things about the shot. But we don't know
the optimal angle at which to release the
ball. The typical optimal angle for a shot
is between 45-55 degrees. This allows the
shot to have a balanced height and speed
on its way to the hoop (Blazevich 2007). A
larger angle will give the shot more
height and a smaller angle will give it a
greater velocity and range. Both of these
aspects are important, a ball that is shot
with a larger height will have a larger
target, but a ball with two much height
won't have the speed and range its takes
to reach the basket.

Countless great shooters have gone through the NBA,
Ray Allen, Steph Curry, Steve Kerr, Jerry West, the list
goes on and on. But what did they all have in common? They
were great at physics! (maybe)Regardless of their grade in high school physics, these shooters have made their living by putting a ball in a hoop from great distances.

Once
the shot is released, it no longer has
any forces acting on it (not including
air resistance) except for gravity. This
means we can use some generalized
equations called the Projectile
Kinematic Equations.

By using these
equations we can find where that ball is going to
land, depending on its initial velocity, mass,
initial position, and time in the air.
