In an old Saturday Night Live skit, actor Garrett Morris rubbed two balloons on his sweater, and they stuck to his chest. It was a science experiment he called “fun with friction.” In video games, ...

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, ...

Experiments suggest that hydrogen bonding explains why a wet surface can have nearly twice as much friction as a dry surface. Record bonding. Experiments have probed the friction between a silicon ...

A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic ...

Experiments demonstrate the breakdown of one of the basic laws of friction at the atomic scale, where more slippery conditions prevail. Friction under the microscope. This scanning electron microscope ...
