Document Summary
Chapter 1: introduction to astronomy: scientific method: => hypothesis - if no contradiction found => physical law. => a body well tested and verifies the hypothesis. => it makes predictions about the outcomes of the future experiments. Has high velocity and attracted to the gravity on earth => helps it circle around earth without dropping to the ground (never-ending rotation). Moon is also earth"s source of satellite. => if mass 1 is more massive, it will attract more force. => if mass 2 is more massive, it will also be bigger (only if both forces are the same size). => if the mass is farther from each other, it will have small force. => long distance = small force; closer to each other = bigger force. => mass(earth) = 5 980 000 000 000 000 000 000 000 kg. => 10 = 10 to the power of 1. => 100 = 10 to the power of 2.
