Worked examples

Gravitation

One sheet for each type of problem, with several worked examples of increasing difficulty: first the computation, then the explanation in words. Each sheet starts with links to the theory it uses.

• 1Gravitational forces between point-like and spherical bodies
• 2Gravitational acceleration on other planets, at altitude and at depth
• 3Satellites in circular orbit
• 4Gravitational field of several masses
• 5Work and gravitational potential energy
• 6Escape velocity and vertical launches
• 7Energy of satellites and Kepler's laws
