Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A bowling ball is dropped in a vacuum chamber. As it falls, the acceleration of the bowling ball
A
decreases
B
increases
C
remains the same
D
None of the above
Explanation: 

Detailed explanation-1: -Because there is no longer any air, there is no more opposing force – this makes the feather and the bowling ball fall to the ground at exactly the same time (see our video below for a demonstration).

Detailed explanation-2: -If you drop a feather and a bowling ball from the same distance anywhere on Earth, they will fall at different rates. The feather will drift breezily to the ground while the bowling ball plunks downward immediately.

Detailed explanation-3: -So, back to the bowling ball and the feather: The reason the bowling ball reaches the ground first is because air resistance has a bigger impact on the feather as it falls. That air resistance slows the feather down while not having much of an impact at all on the bowling ball.
