... Why don’t planets fall? They move around so fast that their speed gives them momentum. Planets don’t fall in toward the sun because they are speeding around their orbits. The sun’s gravity stops them flying off into space. The closer a planet is to the sun the faster it orbits. They orbit in an ell ...

... If you released a stone in mid-air, with no gravity it would not fall. It would just stay there, motionless. Combining this idea with the results of Galileo's “ball on a ramp” investigations, we now have: The Law of Inertia: A body that is subject to no external influences will stay at rest, if alre ...
