E)none of the above

Question

Quizplus · Accepted Answer

In a vacuum, the acceleration due to gravity is constant and does not depend on the mass or weight of an object. The ratio of an object's weight (force due to gravity) to its mass (inertial resistance to acceleration) is the same for all objects, which is the acceleration due to gravity. This is why both a feather and a coin will have equal accelerations when falling in a vacuum, as air resistance is eliminated, allowing both to solely experience the force of gravity.
