Students should be able to:

• Apply Kepler's three laws, including the ellipse, the eccentricity and the speeds at perihelion and aphelion.
• Calculate with Newton's law of gravitation, including superposition, g above and below the surface, and weight against gravity.
• Analyse circular orbits: speed, period and the mass of the central body, including geostationary orbits.
• Use U = −GMm/r for energy conservation, escape speed and the energy of a satellite.

Build the physical idea. Focus: Describe.

Develop the model and method. Focus: Model.

Apply, integrate and transfer. Focus: Conserve and apply.
