What is acceleration?Acceleration is the rate of change of the velocity of an object with respect to time. It is therefore a vector quantity, just like velocity. Meaning that it includes both a magnitude (size) and a direction.
InputGalileo is a unit of acceleration used extensively in the science of gravimetry. It is defined as 1 cm/s².
