Velocity

The velocity of a moving object is a figure, expressed in some unit of measurement, telling us how fast it is moving. 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.

• 1 statute mile ÷ 1 minute = 60 miles per hour
• 40,000 kilometres ÷ 80 days = 20.83 kilometres per hour
• 2,551 nautical miles ÷ 6hr06min = 418 knots

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.
