1. How does Newton’s first law prove that planets are moving in a circular pattern? 2. How does Newton’s third law prove that Earth is moving and the Sun is not?
3.Using Newton’s law of gravitation and the third law of motion, argue qualitatively how the ratio between the orbital period and the radius of a planet do or do not change, based upon Kepler’s third law of motion.

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
