Probably everyone is familiar with the phenomenon: water drops cling to a pane of glass, if it is tilted out of the horizontal plane. Only when a certain angle is reached they slide off. This raises ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Sliding friction between crystal lattices and the physics of cold ion traps are so far non-overlapping fields. Two sliding lattices may either stick and show static friction or slip with dynamic ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, ...

Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...

Show that static friction is greater than kinetic friction by pulling on a wooden box using a spring scale. Clamp the board to a table. (Optional) Select the 50 N scale on the force probe and connect ...

Background With regard to sliding friction sports floor manufacturers focus on comfort and performance aspects of athletes. In relation to safety aspects standardisation bodies rather concentrate on ...
