Gravity: feather vs bowling ball

What is the primary purpose of NASA's Space Power Facility?

• To test nuclear propulsion systems

• To simulate conditions of outer space for spacecraft testing

• To store large quantities of scientific equipment

• To conduct experiments on Earth's atmosphere

How much air is removed from the vacuum chamber to simulate outer space conditions? (pick 2)

• Only 2 grams of air are left

• 30 tons of air are removed

• 800,000 cubic feet of air are removed

• All the air is removed to make a perfect vacuum.

What happens when a bowling ball and feathers are dropped

simultaneously in "normal atmospheric conditions"?

• The bowling ball falls faster than the feathers

• The feathers fall faster than the bowling ball

• Both objects fall at the same rate

• The feathers float upwards

Why does a bowling ball fall with more force than the feathers?

F=ma

• The mass is higher

• It has more acceleration

What was the outcome when the bowling ball and feathers were dropped in the vacuum chamber?

• The bowling ball fell faster than the feathers

• The feathers fell faster than the bowling ball

• Both objects fell at the same rate

• Neither object fell due to lack of air
