Line 1:
Line 1: − + + + + + + + + + + + + − Speed is always a positive value, unlike [[velocity]], which is speed and direction.
Corrected some things and added units.
'''Speed''' is [[distance]] divided by [[time]]. <math>speed=\frac{d D}{d T}</math>
In Physics, speed refers to the magnitude of the [[velocity]] of an object.
'''Speed''' is the total [[distance]] traveled divided by the [[time]] it takes to travel it<ref>Serway and Beichner, ''Physics for Scientists and Engineers'', Fifth Edition</ref>.
<math>Speed=\frac{d D}{d t}</math>
Note that speed is a scalar, therefore it has no direction or sign.
Like velocity, units for it's measurement are [[meter]]/[[second]] and more commonly in informal circumstances [[kilometer]]/[[hour]] and [[mile]]/[[hour]]
