Document Summary
Terminal velocity is the final velocity that something can be. Impulse= change in momentum momentum= measure of inertia in motion/mass in motion. Conservation means you can account for every physical quality of it. Conservation of energy is greater than conservation of momentum. The bigger m1 the stronger the force. Distance between a mass sitting on the earth and radius. If you know circumference, you know radius. What is the acceleration due to gravity on planet moo. Uppercase g is same everywhere in universe. Weightlessness= reading on a scale is 0. If you want an object to go away from earth forever, there is specific speed you must give it. If you shoot something at this speed from tallest tree, it would just circle around earth forever. For less speed, it will fall then hit earth eventually. Higher than 8km/s it will never come back to orbit earth, it will just keep going away.
