Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, ...

In this video, we break down the classic physics problem of a block on an incline with friction. Learn how to calculate the forces at play, including gravitational force, normal force, and frictional ...

An international interdisciplinary research team led by Prof. Richard GU Hongri, Assistant Professor of the Division of Integrative Systems and Design at The Hong Kong University of Science and ...

Why do some cargo loads slide out cleanly while others fight back? Explore the physics, materials, and technology behind ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...
