A feather and a boulder will have equal accelerations when falling under the influence of gravity in a vacuum because
A) the ratio of the object's weight to its mass is the same.
B) gravity does not act in a vacuum.
C) the gravitational force on each object is the same.
D) all gravitational accelerations everywhere are equal.

Question

Quizplus · Accepted Answer

In a vacuum, air resistance is eliminated, allowing all objects to fall at the same rate due to gravity. The acceleration due to gravity is independent of the mass of the objects, meaning both a feather and a boulder will accelerate at the same rate when there is no air resistance to act on them. This is because the ratio of an object's weight (the force of gravity acting on it) to its mass is constant and equal to the acceleration due to gravity.
