• Increase

• decrease

• stay the same

• disappear

When you drop a hammer and a feather on Earth, why does the feather fall slower?

• air resistance causes the feather to slow down

• gravity pulls harder on the hammer than the feather

• gravity pulls harder on the feather than the hammer

• air resistance causes the hammer to fall slower

Air resistance is a force caused by...

• Water pushing against moving objects

• Air pushing against moving objects

• Gravity pushing against moving objects

• Normal force pushing against moving objects
