The question is not how to eliminate friction. The question is how to manage it so it becomes traction and traction becomes forward motion.

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led ...

"Join me as we dive into the core concepts of forces and motion! In this video, we’ll review Newton’s Laws of Motion, explore how forces affect objects, and break down key principles like acceleration ...

Quantum friction represents a subtle, yet profound force emerging from the interplay of quantum vacuum fluctuations and electromagnetic interactions between bodies in relative motion. Distinguished ...

Earlier, we saw that the work done by friction on a particle sliding on a rough surface is negative, causing a loss in total mechanical energy as the particle slides. Here, we will address the ...

The precise control of tiny droplets on surfaces is essential for advanced manufacturing, pharmaceuticals, and next‐generation lab‐on‐a‐chip diagnostics. However, once droplet volume reaches pico- and ...

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 ...

Fluid robot motion is the result of design choices among five options including pneumatics and strain wave gears.

Whether freshly felled or dry, hardwood or softwood, trees are among the largest and heaviest items that move through ...
