The speed of an object falling from a great height is measured in meters per second per second until it reaches terminal velocity (maximum downward speed).
Because if speed is measured in meters per second (m/s) and time is measured in seconds, the SI unit of acceleration is meters per second per second (m/s2). ^_^
Speed is distance divided by time. So : you could have meters per second, or meters per hour, etc.
Speed or acceleration
Speed is a quantity that is measured in meters per second.The previous answer, velocity, is technically incorrect.Velocity is a vector, which consists of a magnitude and a direction.Example: 10 meters per second northwest.Speed, however, is a scalar, and consists solely of a magnitude.Example: 10 meters per second.

Meters per second
Velocity(speed).
The SI unit for tangential speed is meters per second (m/s).
Meters per second
Acceleration is a change in speed, measured per second and so would be meters per second per second or meters per second squared.
Speed is distance divided by time. So : you could have meters per second, or meters per hour, etc.
Speed or acceleration
It is about 9.814 meters per second per second on Earth
Acceleration is the rate of change of velocity.Velocity is the rate of change of position. Since position is measured in length units (for example, meters), velocity is in meters per second, and acceleration is in meters per second per second. In most unit systems, there isn't a specific term for this, though you will sometimes see acceleration measured in "gees", which is the standard accelration due to gravity on Earth, or 9.8 meters per second per second.
The speed of light in a vacuum is about 299,792 kilometers per second, or approximately 186,282 miles per second.
