This site was created by Rice University students who were studying the effects of different forces on Twinkies. We're only showing you the gravity part, but the rest of the site is really cool. In this experiment they drop a Twinkie out of a four story window to see if it suffered any damage. Check it out.
Who really discovered Gravity?
After you take a look at this comic you might wonder. It's worthy of a place in the Sunday comics.
DID YOU KNOW....
What kind of apple did Isaac Newton see?
The apple was from a tree called the Flower of Kent, a variety from around 1629. That tree was so famous that it was looked after until 1814 when it died. Then the wood was used for chairs. But while it was still alive, more trees were grafted from it. Babies of the Newton Flower of Kent Apple Tree have been planted in front of physics labs all over the world. Those trees remind scientists that sometimes the best discoveries come from the simplest places.
In 1969, an American physicist, Joseph Weber, detected gravitational waves made from acceleration. Other scientists are testing his results. It may not always be possible to tell the effects of gravity from the effects of acceleration.
Astronauts study the effect of weightlessness, and scientists use this information to develop new medicines and technologies.
Even though the Earth's pull on the moon is greater than the moon's pull on the Earth, the moon's gravity does affect the Earth. It's the main factor for the oceans' tides.
Astronauts grow several inches out in space without the force of gravity pulling them down, but back on Earth they shrink back to their original Earth height.
