[Brad] just acquired a 32×32 RGB LED matrix and he jumped right into the deep end with his first project. To try out his skills on the device he used an Arduino to drive a slew of pixels with bouncing ...

The physics of a bouncing ball is well understood, but a liquid-filled ball can still surprise scientists. A new study published in the American Institute of Physics' (AIP) journal Physics of Fluids ...

[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 ...

Skipping elastic balls off water is much easier to do than trying to make stones "hop" across the surface of a lake, but a new study of water-impact physics isn't all fun and games — the research ...

A physics demonstration shows how bouncing balls can appear to keep moving endlessly, explaining the energy transfer and ...

There are so many real-world physics problems involved in running. Lots of physicists have been inspired, for instance, by the crazy-fast speeds of Usain Bolt. Just take a look at this paper, "On the ...
