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, ...

The rotation of stars in galaxies such as our Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact stars in the middle and ...

Fig. 1 The measured time-resolved KER spectrum (A) and the measured photoion momentum distributions at different delays (B) of O2 molecules. The coupled electronic and nuclear motions within a single ...

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 ...

Magnetic rotation and antimagnetic rotation represent distinct mechanisms by which atomic nuclei generate angular momentum in systems that exhibit little or no permanent quadrupole deformation. In ...

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

Dynamic galaxy: can the rotation of the spiral galaxy NGC 1232 be explained by MOND? (Courtesy: ESO) Can modified Newtonian dynamics (MOND) explain the curious behaviour of rotating galaxies? Two ...
