Posted by Dan on Sunday, July 8, 2012 at 7:39pm.

You are explaining why astronauts feel weightless while orbiting in the space shuttle. Your friends respond that they thought gravity was just a lot weaker up there. Convince them and yourself that it isn't so by calculating the acceleration of gravity 248 km above the Earth's surface in terms of g. (The mass of the Earth is 5.97 1024 kg, and the radius of the Earth is 6380 km.)
