Assuming the books are stacked in a neat, vertical pile on a table that it is itself horizontal to the earth and at an altitude comparable to sea level (I.e. not on a ship at sea, or on an airplane) then the force that is acting on the stack of books is described by the formula: \[F = ma\]("force" = mass * acceleration) Assuming the mass is in kilograms, the acceleration due to gravity on the Earth is \[9.80665 m /s^{2}\] and the resultant force is in Newtons. The magnitude of the acceleration is negative because it is "pulling" the stack of books toward the center of the Earth. A cool online force calculator is available: “http://www.ajdesigner.com/fl_force/force.php” I hope this helps, David
