Speed cameras use multiple kinds of technology to get driver's speeds. But they're not perfect, and there are several issues ...

Here on land, the speed of a vehicle is recorded in either miles per hour or kilometers per hour. In either case, determining how fast you're moving on land is fairly simple because you can see ...

Many measurements start with sensors, be they temperature, strain, light, position, or other physical properties. Accurately measuring the distance to and speed of an object has challenges relating to ...

A crankshaft may experience irregular rotational speed patterns caused by a combustion engine’s discrete firing process. These excite components of the driveshaft, which causes rotational vibrations ...

Bucknell University Professor Katelyn Allers, physics & astronomy, is publishing the first measurement of atmospheric wind speed outside the solar system using a new technique she developed. Her study ...

Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material's ...
