A feather and a coin dropped in a vacuum fall with equal
A)forces due to gravity.
B)accelerations.
C)kinetic energies.
D)none of these

Question

Quizplus · Accepted Answer

In a vacuum, there is no air resistance, which is the main factor that affects the rate at which objects fall. Thus, all objects, regardless of their mass, will experience the same acceleration due to gravity. Therefore, both the feather and the coin will fall with equal acceleration, i.e., choice B is correct. However, the force due to gravity that each object experiences is not the same because force depends on the mass of the object, i.e., choice A is incorrect. Also, since the feather and coin have different masses, they will have different kinetic energies as they fall, i.e., choice C is incorrect. Thus, the best choice is B.
