There are several electronic measurement systems that measure the velocity, power, and effectiveness of a lift.

Kilometres per hour is a unit of measurement, which measures speed or velocity.

Almost every effect of fluid motion must at some time have been tried as a means of measuring velocities.

By independently measuring the velocity and distances to galaxies, the value of Ho could be determined.

Riding the roller coaster, he said, would offer an opportunity to measure the velocity of circular motion.

For measuring velocity and length on moving surfaces, laser surface velocimeters are used.
