Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On this ...

The film explains the concept of uniform motion, highlighting that it involves an object moving in a straight line at a constant speed. Examples include a jet and a car that move equal distances in ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Baryons, composite particles made up of ...

In the world of particle physics, you are never alone — quite literally. Every moment there is an invisible rainstorm of subatomic particles falling down on us from space. Unlike the kind of matter we ...

Stefan Hutzler and Denis Weaire are in the School of Physics, Trinity College Dublin, Ireland. Their postgraduate student Ali Irannezhad currently performs his experiments in his home in Tehran, Iran.

Fifth force experiment: the cold neutron guide hall at NIST’s Center for Neutron Research in Maryland. (Courtesy: NIST/Yiming Qiu) An improved search for a potential fifth force of nature is one of a ...

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works — a prospect that has the field of particle physics both baffled and ...

Tests of quantum weirdness and its potential real-world applications have been recognized with the 2022 Nobel Prize in physics. At some level we are all subject to quantum rules that even Albert ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...
