The velocity of a moving object is the distance it travels in unit time. It is usually determined by dividing a fixed distance over the period of time required to travel that distance. The word speed means about the same thing. Technically, in physics, velocity not only indicates speed, but also the direction of motion.

The current understanding of physics holds that c, the speed of light through a vacuum (about 300 million meters per second), is the absolute upper limit of velocity for any tangible object.
