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 ...

Collision physics is a research area within atomic, molecular, and optical physics that investigates the fundamental processes occurring when particles such as atoms, ions, electrons, or molecules ...

Researchers have found that high-speed particles can rebound more strongly from wet surfaces than from dry ones, due to a liquid film changing shape during impact. Experiments and simulations showed ...

Ready to go: the Belle II experiment will run on Japan's SuperKEKB accelerator. (Courtesy: KEK) The first electron–positron collisions occurred at an upgrade to one of Japan’s premier particle-physics ...
