This bundle includeslecture notes on Newton's Law of Universal Gravitation, weightlessness and orbits as the result of free fall around a curved Earth, and motions that result from a centripetal force (including vertical circles, horizontal circles, and orbits) as well as additional information (how the calculus Newton developed leads to the inverse square law, demo and handouts for vertical and horizontal circular motion, escape velocity and orbits as bound systems)circular motion lab and analy
