Gravity in Action

Play and experiment with these games and animations about gravitational pull.

Observe the effects gravity has on objects, planets and stars. Gravity keeps the planets in their orbits around the sun. Gravity "glues" us to the surface or the earth. Gravity confines the atmosphere to a layer around the earth.

Freefall on the Earth


Falling objects on the earth are subjected to air-friction. Experiment with several falling objects.

Projectile


Shoot with a cannon and observe the motion of the cannon ball.

Satellite game


Learn about satellites around the earth and then play a game where you have to dock a satellite with a space station.



Gravitational force between Planets


Grab one of the planets in this two-planet system and swing it around. With this animation you can learn about how planets behave in a gravity field.

Earth - Moon System


This animation shows the Moon circling around the Earth as seen from a point in space far to the South. Learn more about our Earth - Moon System. Gravity is the force acting between the objects.

The Sun - Earth - Moon System


The Earth - Moon sytem as seen from a point in space far to the South. Learn about seasons.

Question: Is the Moon moving up or down when you see it rising?
