If you could stand on the surface of Uranus (you can't, for so many reasons), you would experience 89% the force of gravity that you experience on Earth. {/eq}. Rather than undergoing an acceleration, objects in free fall travel along straight lines on the curved spacetime. Uranus has a thick atmosphere made of methane, hydrogen, and helium. The surface gravity on Uranus is about 86% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 86 pounds on Uranus (assuming you could find someplace to, well, stand).
