Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Orbital mechanics can be a bit counter-intuitive. We have to slow down an orbiting space craft to convert kinetic energy for gravitational energy. The orbital altitude is raised at its highest point ...

How does its orbital speed compare to that of other solar system planets? How fast you need to move to keep in a circular orbit around another body is dictated by how far the two bodies are ...

Orbital sanders measure their speed in orbits per minute (OPM), which typically ranges from 7,000 to 13,000. The faster the pad spins, the more material the sandpaper removes, and the faster it works.

In 2006, the Air Force announced the development of its own variant of the space plane, known as the X-37B, designed to operate with an orbital speed of nearly 17,500 mph for up to 270 days.

Using the UVES spectrograph on the VLT they measured their orbital speed, and noticed that their orbits change over time. After carefully ruling out other explanations, they concluded that the ...
