A great shooter feels the perfect arc. The physics behind it: the ball must drop into the hoop steeply enough to see a wide enough opening — but not so steep it needs a moonball.
Basketball Shot ArcLive
the physics of a jump shot
Controls
Presets
A basketball shot must arrive at the rim from above to have a chance of dropping in. Too flat and the ball meets the front rim; too steep and it needs excess speed. Coaches prize an entry angle around 43–47°, which maximizes the effective size of the hoop the ball sees. Higher release points let shorter players shoot flatter and still score.

How it works
A basketball must enter the rim from above to have room to fall through. Too flat an arc meets the front of the rim; too steep wastes energy and control. An entry angle around 43–47° maximizes the effective target the ball sees. A higher release point lets a shooter use a flatter, more repeatable arc while still scoring — the geometry every jump shot obeys.
