NASA's Space Power Facility and Gravity Experiments

Where is NASA's space power facility located?

• Cape Canaveral, Florida

• Cleveland, Ohio

• Houston, Texas

• Pasadena, California

What is the primary purpose of NASA's space power facility?

• To store spacecraft

• To train astronauts

• To test spacecraft in outer space conditions

• To launch spacecraft

Why was the vacuum chamber built with a concrete skin?

• To provide radiation shielding and act as an external pressure vessel

• To make it lightweight

• To make it look aesthetically pleasing

• To reduce the cost of construction

What was the original purpose of the vacuum chamber when it was built in the 1960s?

• To train astronauts

• To conduct space missions

• To store nuclear waste

• To test nuclear propulsion systems

What did Galileo's experiment demonstrate?

• Objects fall at the same rate regardless of their weight

• Light objects fall faster than heavy ones

• Objects do not fall in a vacuum

• Heavy objects fall faster than light ones

Why do feathers fall slower than a bowling ball in the presence of air?

• Because of their weight

• Because of air resistance

• Because of their shape

• Because of gravity

How long does it take to pump out the air from the chamber to create a near-perfect vacuum?

• Four hours

• Three hours

• Two hours

• One hour

What was observed when the ball and feather were dropped in the vacuum chamber?

• Both fell at the same rate

• Neither fell

• The feather fell faster than the ball

• The ball fell faster than the feather

According to Isaac Newton, why do the ball and feather fall?

• Because of their shape

• Because of their weight

• Because of gravity

• Because of air resistance

How did Einstein view the falling of the ball and feather differently from Newton?

• He believed they were falling due to their shape

• He believed they were falling due to air resistance

• He believed they were not falling but standing still

• He believed they were falling due to their weight
