Universal Gravitation and Orbital Motion

A self-checking practice quiz on universal gravitation and orbital motion for a calculus-based physics course: Newton’s law of gravitation, the inverse-square law, gravitational field strength and potential energy, orbital motion and velocity, Kepler’s three laws, escape velocity, and satellites. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
