How is Motion Measured?

Answer

The rate of motion of an object is usually measured in units of velocity, such as miles or kilometers per hour or in meters per second squared. This is done by calculating the specific distance the object traveled over a known period of elapsed time. Velocity motion can also be measured electronically by the use of a RADAR speed detector which projects radio waves at a moving object and calculates the time interval for the waves to bounce back to the detector.
