Friction and Gravity. 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?. EQ: What changes an object’s motion?. Friction and Gravity.

Gravity. gives the Universe its structure. It is a universal force that causes all objects to pull on all other objects everywhere. Earth, Moon, and Sun Gravity and Motion Isaac Newton was the first scientist to explain what keeps the Earth and Moon in orbit Force – a push or a pull There is a force acting between the Earth and the moon that keeps them in orbit GEOLOGY & MINING RESEARCH INSTITUTE Systemic Target Oriented Prognosis Technology November 2012 CONTENT 1.
