# Velocity Unit

IB
For velocity unit, is it, for example, 30 m/s^2?

whozum
meters per second, m/s

m/s^2 is acceleration.

Assuming that you are measuring distance in meters and time in seconds, then, since velocity is "distance/time", its units would be m/s.
Acceleration, which is "velocity/ time" would be (m/s)/s= m/s2.

Of course, if you measure distance in miles and time in hours, then velocity would be "miles divide by hours", mi/hr or "miles per hour".

how do u calculate velocity WITHOUT time?

Eh? What does that have to do with this thread?
