Occasionally there are physics lab demonstrations that I think are pretty awesome but that my students just think are "meh." This is one of those cases. The basic idea in this demo, which I used in my ...

Segment 3G: Circular Motion We explore the concept of circular motion. Segment 3G: Circular Motion We travel to an amusement park to explore circular motion. We work through an example problem and ...

Did you know that, at a certain point on a moving wheel... there's no motion? Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right?

Learn the key differences between centripetal and centrifugal forces, their real-world applications in physics, and how they shape our understanding of circular motion. When you purchase through links ...

Researchers have made a revolutionary find after learning that air bubbles in liquid exhibit an unexpected ‘galloping’ motion when shaken vertically. Surprisingly, instead of following the expected up ...

When humanity first started studying motion, circles posed a peculiar puzzle. Why do planets sweep endlessly around the Sun without flying off into the void of space? Why does a stone swung on a ...
