When humanity first started studying motion, circles posed a peculiar puzzle. Why do planets sweep endlessly around the Sun without flying off into the void of space? Why does a stone swung on a ...

The tendency of objects to maintain their state of motion is called inertia. On Earth, moving objects commonly come to rest without continued application of a force due to the unbalanced forces of ...

Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...

A new experiment encodes quantum information in the motion of the atoms and creates a state known as hyper-entanglement, in which two or more traits are linked among a pair of atoms. Manuel Endres, ...

Advances in linear motors and hybrid actuators are pushing motion systems toward higher precision, speed and efficiency. A key part of achieving this performance is the integration of drives with ...

Humanity’s need to track the Moon’s changing phases and motions is ancient. Mammoth hunters used the Moon as a timekeeper, carving crescent-shaped notches into bone and tusk. Sumerian astronomers ...

An introduction to the core principles of braking systems in mechanical design. A high-level introduction to the application of braking systems in machinery and equipment, as well as their relevance ...
