A feather and a coin will have equal accelerations when falling in a vacuum because
A)their velocities are the same.
B)the force of gravity is the same for each in a vacuum.

D)the ratio of each object's weight to its mass is the same.
E)none of these

Question

Quizplus · Accepted Answer

The acceleration due to gravity in a vacuum is constant, and it depends only on the mass of the object. Thus, objects with different masses but the same weight (i.e., the same ratio of weight to mass) will experience the same acceleration, which is why a feather and a coin would have equal accelerations in a vacuum.
