Document Summary
Ast101 week four october 4th, 2016. Came up with an accurate description of the motion of the planets. Planets orbit the sun in an elliptical pattern, with the sun at one focus and the moon at the other focus. Planets trace out equal area in equal time. A planet"s orbital period depends on its distance from the sun as p2 = a3. Uses a telescope to look at the sky. Didn"t make sense for earth to have different rules from the heavens because god controls it all. Revolutionized math and science: (co)invented calculus, presented the idea of force and the laws of motion, described the law of gravity. Eg: the car is travelling 60km per hour. Eg: the car is going due north at 60km/hour. Acceleration: the rate of change of velocity. E. g: the car is changing speed from 0 km/hr to 100 km/hr in 9s. (change in speed)
