A feather and a coin will have equal accelerations when falling in a vacuum because
A) their velocities are the same.

D) the force of gravity is the same for each in a vacuum.
E) none of these.

Question

Quizplus · Accepted Answer

In a vacuum, all objects fall at the same rate because the acceleration due to gravity is constant and does not depend on the mass of the object. The ratio of an object's weight (force due to gravity) to its mass (inertia) is the same for all objects, leading to the same acceleration.
