What happens when you jump on a sled on the side of a snow-covered hill?. What happens at the bottom of the hill?. Friction and Gravity. Why does the sled’s motion change on the side of the hill and then again at the bottom?. Gravity. Gravity is a force that for us is always directed downwards. But to say that gravity acts 
downwards is not correct. Gravity acts down, no matter where you stand on the Earth. It is 
better to say that on Earth gravity pulls objects towards the center of the Earth. So no matter 
where you are on Earth all objects fall to the ground. . Mars Society Conference. September 2017, UC Irvine. Joe Carroll .
