Question

David Scott's experiment shows that all objects, regardless of their weight, fall equally in the absence of: a. The gravity

b. The air
c. The pressure
d. The gravitational force

Answer 1

b. the air

Step-by-step explanation:

David Scott's experiment was performed on the moon, where there is gravity but there is no air. This experiment consisted of letting a hammer and a feather fall at the same time. The result was that the two objects touch the ground simultaneously.

Since these two objects obviously have a different mass, the experiment shows that in a vacuum, objects fall with the same acceleration regardless of their mass.
