Gravity was discovered 3 centuries ago by Sir Isaac Newton. A mathematician and physicist by profession, Newton discovered gravity sitting under a tree and observing falling apples. After further research, Newton discovered that gravity exists between all objects and that gravity is essential for normal life on earth as it helps us from floating away into space.
Gravity exists for many reasons; it keeps the earth rotating in its orbit and keeps it at a certain distance from the sun, keeping our planet at a perfect distance from the sun, preventing it (more…)
Gravity is a universal force that binds together planets within solar systems, and keeps our feet on the ground walking around planet Earth. The sun is very important to life on Earth, as it not only provides us with warmth and light, but affects our gravity.
The sun is a very large star, and is the largest celestial object in our solar system. The sun is 1,390,000 kilometers in diameter, so it’s size creates a very large magnetic pull. Thanks to the sun’s huge magnetic pull, it creates (more…)
Since the first astronaut was sent into space, there’s been a great interest in zero-gravity conditions for experiments. Most experiments have focused on how a lack of gravity affects living organisms.
Other experiments have looked at chemical reactions and processes without the presence of gravity. While the International Space Station provides the ideal platform for zero-gravity experiments, NASA and other researchers have conducted many using aircraft in free-fall.
The most important experiments have examined the harmful results of humans living in space for extended periods. Initial experiments showed the loss of bone (more…)
If your kids have expressed interest in learning more about the world’s gravitational forces it’s time you spent a few moments letting them explore. There are tons of resources out there to help educate them so here are a few of our good parenting suggestions…
Take them to a Science Museum – There are bonafide science museums all over the country and they’re great at getting hands on and interactive with the kids in your life. They can drop things from high (more…)
