<!--In many situations, objects do not move at a constant speed. For example, if a car goes 60 miles in 2 hours, its average speed during that time is 30 miles per hour, but its instantaneous speed may have varied.

Celeritas est quam celer res movit, mathematice magnitudo velocitatis rei, unitatibus usitatis metrorum per secundum divisorum.
In physica quidem celeritas correspondit distantiae instantaniae quam corpus quoddam transcurrit in tempore. Denotata ab , celeritas rei igitur datur a formula
- .
ubi dx est distantia differentialis traversa et dt est tempus differentiale huius motionis.
De mensuris vulgo in usu
Communiores physicae celeritatis unitates sunt:
- m / s (metra per secundum),
- km / h (chiliometra per horam). Si chiliometra per horam in metra per secundum convertere volueris numerum per 3,6 divides. Exempli gratia 72 km/h = 20m/s. Etenim sunt 3600 secunda in hora et mille metra in chiliometro ː millies igitur multiplicabis et per 3600 summam divides.
