A-level Physics Unit 7.2 Gravitational fields - 7.2.3 Orbits of planets & satellites (New AQA spec)

In lesson 4 of the gravitational fields unit students look at the orbits of planets and satellites. The lesson is introduced in part by a couple of videos that challenge their known models of the motion of the solar system.
The lesson goes on to discuss properties of orbits such as radius, orbital speed and orbital period and the derivation of the relationship between orbital period and radius is gone through in detail (this is required knowledge in the specification).
Students then go on to learn about the energy of satellites, escape velocity and how to calculate it, as well as synchronous orbits and geostationary satellites (including their applications).

These A-level lesson power points are detailed and tailored to guide students (and teachers) through the new physics A-level specification (and are referenced accordingly). Each has outlined at the start a clear progression through the topic and the relevant section from the specification. Lessons begin with a starter activity to get students thinking and develop problem-solving skills before they progress with new theory and practice. All power points contain practice questions with answers included at the end.

The high level of detail in these lessons will particularly suit those who are newer to teaching physics at A-level or whose subject knowledge may be a little rusty.
