Gravity science

Will a ball and a feather hit the ground at the same time? Find out with the collection of gravity experiments and learn about Isaac Newton and Galileo

It is thought that Isaac Newton’s theories on gravity were inspired by seeing an apple fall from a tree. https://www.facebook.com/scholarslearning/photos/a.744091828942643.1073741828.731990170152809/885587038126454/?type=1&theater

Any two masses are attracted towards each other by gravity. This force of gravity causes the Moon to change direction to make it orbit around the Earth.

Albert Einstein's theory of relativity is the basis for our understanding of the universe, but if you still aren't quite sure how it works, this video does an excellent job of explaining.

As the legend goes, Isaac Newton came up with his theory of gravity after a falling apple landed on his head. But did it really, or was it just a farce?

LIGO scientists are set to announce discovery of gravitational waves.

Perhaps the most important problem in physics is how gravity and quantum mechanics fit together, and strange fluctuations in gravitational waves could help us figure it out

As you've most likely taught your students, gravity is the force that exists between any two objects that have mass. Weight is a measure of the force of gravity pulling on

The more we learn about the universe, the more questions seem to arise. Our picks for the biggest open questions remaining in physics.
