Have you ever noticed when moving furniture that heavy objects are easier to move if you rotate them at the same time as you push? Many people intuitively do this right. An international research team ...

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

The less work required to translate an object, the better. Avoiding sliding friction — a major sinkhole of applied force for motion — is accomplished through rolling. A: Ironically, with increased ...
