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, ...

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...

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 ...

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 ...
