These sites explain how the earth’s gravity works. Includes photographs, simulations, videos, hands-on activities, and online quizzes. Included are eThemes resources on mass versus weight and force.
What would happen if you popped a water balloon in space? Find out by watching three videos showing astronauts conducting this experiment.
This interactive simulation helps beginners visualize and understand gravity. Choose different objects to see how they would fall to the ground. NOTE: The site includes ads.
Find out what you would weigh on another planet. Type in your weight and click "Calculate."
Read the instructions, then build your own object and see what happens when gravity is turned off.
This site has three interactive games for testing your knowledge about gravity. The experiments are based upon those done by Galileo.
Students can learn how the human body acts in zero gravity. Students can listen to this story by clicking on "Streaming Audio." Teachers can scroll down to the "Classroom Center" for PDF files.
Learn how to calculate the mass of the Earth using Newton's Law of Gravitation.
Learn the difference between the two similar, but distinctive terms of gravity and gravitation. Click on "The Law of Universal Gravitation" link to read more about gravitation.
NOTE: The site has pop-up ads.
This site has answers to common questions about gravity.
If a hole could be dug from one side of the Earth to the other, what would happen to a ball that was dropped in? Find an answer here.
Play the gravity game and notice how gravity pulls the ship down to the planet's surface.
NOTE: The site has ad banners.
These sites cover the basic concepts of physics. Learn about force, motion, and friction using interactive simulations where you can manipulate the variables.
