Coronal mass ejections (CMEs), emissions of magnetized ionized gas from the Sun, can damage satellites and communication technology, so being able to predict where they are heading and how much energy ...

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 ...

Anyone who has played billiards knows instinctively about elastic collisions or they would never be able to sink a ball. But how many have made the observation that, except in cases where there are ...

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 ...

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 ...

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 ...

Newton’s Third Law of Motion concerns equal and opposite forces. It states that, “If A exerts a force on B, then B exerts an equal but opposite force on A”. Forces always occur in ‘Newton pairs’ and ...
