Why does a hammer fall faster than a feather?

• Because the hammer is heavier

• Because the feather is lighter

• Because of air resistance

• Because of gravity

• They pick up speed as they drop

• They slow down as they drop

• They don't fall at all

How did Galileo measure the acceleration of falling objects?

• By dropping objects off the Leaning Tower of Pisa

• By using a stopwatch

• By weighing the objects

• By using a laser

What is the mathematical relationship between distance and time for falling objects?
