Earth vs. Moon - Relative Size

The Moon is much smaller than the Earth. Therefore, it pulls less. Watch some footage from the moon landings to see for yourself!


Astronauts on the moon – notice how they get around. Are they walking normally? How much is the Moon’s gravity pulling them?


Dropping a feather and hammer on the moon – This experiment should look familiar. We did something like this in class together. The difference is – no air on the moon, so the feather won’t float. Also notice how much time it takes for both objects to hit the ground.


Throwing a hammer on the moon – Notice how high the hammer goes, and how long it takes for it to come down. What would that look like on Earth?
