Cosmic filaments are among the largest structures in the Universe, and they rotate. In a new study that stacked thousands of filaments together, they were observed to be rotating along their ...

Rotational dynamics explained through a 1935 physics textbook. Explore classic diagrams and timeless explanations that break down torque, angular motion, and rotational principles in a clear, ...

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 ...

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?

Scholars in the Institute of Bio-inspired Structure and Surface Engineering (IBSS), Nanjing University of Aeronautics and Astronautics (NUAA) used a three-dimensional locomotion video-recording and ...

To determine the short-term effects of simulated microgravity on mesenchymal stem cell behaviors—as a function of clinorotation speed—using time-lapse microscopy. We compared cell responses at ...

Quite a few Olympic events involve flipping and twisting, including gymnastics, diving, and trampoline. You might ask, "What is the difference between a flip and a twist?" I am going to give my ...
