A-level Physics Unit 7.2 Gravitational fields - 7.2.3 Gravitational potential (New AQA spec)

In lesson 3 of the gravitational fields unit students are introduced to the concept of gravitational potential and grapple with why values of gravitational potential are negative. The learn to calculate
gravitational potential in a radial field and work done in moving a mass between points of different gravitational potential (including the special case of equipotentials that lays the ground work for next lesson on orbits). They then progress to look at graphical representations of variations of g and V with r and how to calculate these variables from the graphs.

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.
