| Content | Opportunities for skills development |
|---|---|
Orbital period and speed related to radius of circular orbit; derivation of Energy considerations for an orbiting satellite. Total energy of an orbiting satellite. Escape velocity. |
Synchronous orbits.
Use of satellites in low orbits and geostationary orbits, to include plane and radius of geostationary orbit.
MS 0.4 Estimate various parameters of planetary orbits, eg kinetic energy of a planet in orbit. MS 3.11 Use logarithmic plots to show relationships between T and r for given data. |
