Elastic collisions in one dimension are a clear example of physics in action, where both momentum and kinetic energy remain unchanged. With the right formulas, you can predict exactly how objects will ...

This is at least my ninth year of writing about Pi Day—here is my post from 2010. Of course it's called Pi Day because the date, 3/14, is similar to the first three digits of pi (3.1415 …). At this ...

The quantum nature of interactions between elementary particles allows drawing non-trivial conclusions even from processes as simple as elastic scattering. The ATLAS experiment at the LHC accelerator ...

Segment 4C: Collisions We differentiate between elastic and inelastic collisions Segment 4C: Collisions In this segment, we differentiate between elastic and inelastic collisions. The conservation of ...

Master elastic collisions in 2D by learning the common pitfalls and their solutions! This video walks you through typical mistakes, step-by-step calculations, and strategies to correctly solve ...

Exploiting the hyperfine structure in repulsive light-assisted collisions (LAC) on a 87-Rubidium atom pair in an optical tweezer. When atoms collide, their exact structure—for example, the number of ...

Protons accelerated almost to the speed of light can collide similarly to billiard balls. However, since protons are quantum particles, from measuring such collisions we can learn unobvious things ...

When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their nuclei—has a lot to say about how they bounce off each other. This is ...
