When you look at a speedometer in a car, you are seeing the instantaneous speed. This equation gives the average speed of an object over an interval of time. Physics The rate or a measure of the rate of motion, especially: a. See more. How to use speed in a sentence. Speed, according to its technical definition, is a scalar quantity that indicates the rate of motion distance per time.Its units are length and time.

The car may be travelling at 50 mph at this moment, but it may slow down or speed up during the next hour. Define speed. Tangential speed = radial distance x rotational speed. n. 1. Speed is a scalar quantity, it does not account for direction, while velocity is a Italian physicist Galileo Galilei is usually credited with being the first to measure speed by considering the distance covered and the time it takes. The measurement of speed can reflect two different scalar quantities. !miejsce kontroli radarowej → Jaká je nejvyšší povolená rychlost na této silnici? The SI units for speed are m/s (meters per second). If it isn't moving at all, it has zero speed.


In everyday usage, kilometers per hour or miles per hour are the common units of speed. While you may have been going 60 miles per hour for a moment, your average rate of speed for ten minutes might be far more or far less.
