Question

Which would fall with greater acceleration in a vacuum a leaf or a stone?

Answer 1

Because its a vacuum, there's no air resistance, they will fall at same time
Applying gravity acceleration rule g=9.8m/s which is taken as 10m/s sometimes.

Answer 2

Answer:

They will both have the same acceleration

Explanation:

Because its a vacuum, which ordinarily means it will be closed (unless otherwise stated), there will be no opposing forces (like air interference) to each of there acceleration due to gravity - each of them will have an acceleration due to gravity of 9.8 m/s2 (or approximately 10 m/s2) and will hit the "ground" at the same time if "dropped" at the same time.

Here, the masses will not be considered because there are no obstructions/opposing forces.
