Photons have both linear and angular momentum, and the influence of one or both becomes evident during scattering or absorbing processes. For example, the transfer of linear momentum from photons to ...

Researchers have unseated a previous theory for the mechanism underlying bacterial flagella movement, changing our ...

Using a rotation tester when installing a motor saves time and prevents problems such as driving the load backward. In some cases, you must get the motor rotation correct or massive damage will occur.

• Hall-effect sensors used to control dc-electric motors can detect motor rotation direction, and rpm. • Improper inflation of aircraft tires drastically shortens tire life span, leading to premature ...
