1 Conservation of Momentum

2 Angular Momentum

3 Newton’s Law of Gravitation

4 Kepler’s Laws Explained
All three of Kepler’s law can be explained by Newton’s gravity Ellipses are special cases: bound orbits 2nd law follows from central force and conservation of angular momentum Newton’s form of Kepler’s 3rd law: p2 = p2 a G(M1+M2)


6 Exact Time of High Tide


8 Tidal Force

9 Ocean Tides Ocean levels rise and fall twice per day
The level of tides is related to the lunar phases Ocean tides are a combined effect of the Moon’s and Sun’s tidal forces
