[Eric Archer] constructed an analog computer to model the physics of a bouncing ball. The core is a TL074 opamp that does all the integral math. He had no trouble finding descriptions of analog ...

Simulating a bouncing ball is a classic programming challenge that requires accurate collision detection algorithms to ensure that the ball doesn’t break the rules of physics. Poorly written ...

But how exactly do players make the ball move through the air or bounce off the court like that? The physics underlying the effect is complex. But the easiest way to explain it is to consider the ...
