Mt/sec2 or ft/sec2 (Meters per second squared or feet per second squared). For example a free falling object has an acceleration figure of 9.8 Mt/sec2. Also: A g is a unit of acceleration equal to the acceleration caused by gravity. Gravity causes free-falling objects on the Earth to change their speeds at rates of about 10 m/s each second. That would be equivalent to a change in speed of 32 ft/s in each consecutive second. If an object is said to experience 3 g's of acceleration, then the object is changing its speed at a rate of about 30 m/s every second.

"In physics, acceleration is defined as the rate of change of velocity, or as the second derivative of position (with respect to time). It is then a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second² (m·s^-2). " Source and further information: http://en.wikipedia.org/wiki/Acceleration
