The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. Acceleration and Weight Newton's second law of motion explains the weight of objects. Weight is a measure of the force of gravity pulling on an object of a given mass. It's the force (F) in the acceleration equation that was introduced above: a = F m This equation can also be written as: F = ma The acceleration due to gravity of an object equals 9.8 m/s2, so if you know the mass of an object, you can calculate its weight as: F = m 9:8...
