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.
InputInches Per Square Second is an acceleration unit equal to 2.54 centimeters per square second.
Standard Gravity (also called: Standard Acceleration due to Gravity) is the gravitational acceleration of an object in a vacuum near the surface of the Earth.
