I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...

Cross-flow turbines, also known as vertical-axis turbines, are attractive for power generation from wind and water currents. Some cross-flow turbine designs optimize unsteady fluid forces and maximize ...

Learn how to calculate the angular velocity required to create artificial gravity in a rotating system. This video explains the physics behind centripetal acceleration, rotation radius, and angular ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

In this video, we determine the maximum angular speed a coin can have on a rotating turntable without slipping. By analyzing static friction and centripetal force, you’ll learn how rotational dynamics ...
