The time rate of change of an object's [[velocity]].<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref>. For an object to undergo an acceleration, a [[force]] needs to be exerted on the object. An example is a falling object on [[Earth]], which is subject to a [[gravity|gravitational force]]. The resulting acceleration is independent of the mass of the object, and is 9.8 [[meter]] per [[second]] squared, the gravitational acceleration ''g''<ref>Marcelo Alonso and Edward J.
