Document Summary
2:41 pm: the equilibrium theory, greeks were first to write equations trying to explain the tides, the pull of gravity between two bodies is proportional to the mass of the bodies and the. Sir isaac newton formalized this theory though distance between them. In simplified theory, it is assumed that the sea floor does not influence tides and there are no interfering continents: gravitational forces. Lunar cycle: timing of cycles change each day because lunar days are longer than solar days, 24 hours, 50 minutes. So high and low tides change by 50 minutes each day as the tides follow the lunar day. Lunar day: time it takes for a single point on the earth to rotate and come back in line with the moon. Rotating all about 1 point: different in high and low tide is greater the further you get away from these points, tidal currents.
