If you were on a planet that had twice the mass of the Earth, but was the same size, by what factor would your weight change? Why (for example, would it double, triple, quadruple, half, quarter, etc.)
Many people mistakenly believe that astronauts that orbit the Earth are "above gravity." Calculate the acceleration due to gravity (g) for space shuttle territory, 200 kilometers above the Earth's surface. Earth's mass is 6 x 1024 kilograms and its radius is 6.38 x 106 meters (6380 kilometers). Your answer is what percentage of 9.8m/s2?
What happens to the separation distance between two people if they both walk north at the same rate from two locations on Earth’s equator? And just for fun, where in the world is a step in every direction a step south?
