Kepler’s Laws Revisited
Previous: Ellipse Kepler thought that, in the Solar System, the planets rotate in elliptical trajectories with the center of the Sun in one focus. Newtonian mechanics unveiled that Kepler’s assumption was not fully correct. The Sun is not located in … Continue reading

Escape Velocity
Previous: Newton’s Laws How fast must an object travel to escape a gravitational potential well? At the escape velocity, or faster. G = Gravitational constant, 6.67300 × 1011 m3 kg1 s2 M = Mass of the planet (or whatever it is) r = distance … Continue reading
