Two objects of different mass are dropped from the same height in a vacuum. Which statement is correct?

Answer and explanation

Correct answer: D. They reach the ground at the same time

In a vacuum every object falls with the same acceleration .
Answer: They reach the ground at the same time.
Why not the others: The heavier one lands first: acceleration does not depend on mass in a vacuum. The lighter one lands first: acceleration does not depend on mass in a vacuum. Neither lands because of buoyancy: there is no buoyancy in a vacuum.
