Conservation of Momentum

Angular Momentum

Newton’s Law of Gravitation

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 = 4 p2 a3 G(M1+M2)

Exact Time of High Tide

Tidal Force

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
