Question 1 2 pts In the video shown of footage from the moon, the astronaut shows that the free fall of a hammer and a feather, which weigh very different amounts, build speed by the same amount at the same time. That is, they fall together even though the hammer is heavier. Another way to say this is that they have the same free fall acceleration. This is true because on the moon there is no air resistance on either the hammer or the feather. The moon has no atmosphere so it has no air. The hammer and feather fall through EMPTY space; also known as the vacuum. The astronaut thanks Galileo Galilei in the video from the moon. I wonder if Galileo would have ever imagined that a person would thank him from the moon. What kind of bird is the feather from? O Turkey Falcon O Eagle Chicken Next >
