In the gaseous phase, vibrational-, rotational- and translational-energy transfer between small molecules can be observed experimentally from time-dependent optical spectra. Populations in the ...

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 ...

Translational and rotational motion are compared and contrasted. Rotational Inertia &Torque: Translational and rotational motion are compared and contrasted. Students learn to distinguish between ...

Unlock the secrets of torque and rotational equilibrium in this clear and engaging physics explanation. Using the example of a hanging sign, we break down how forces, distances, and angles work ...

Computational methods that can simulate reactions, how a molecule behaves in a certain environment and what properties a material will exhibit (amongst other areas) have been gaining interest in ...

A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics.

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 they all have the same ...

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 ...
