GCSE AQA Physics - P1.4-6 - Gravitational potential, kinetic energy, and elastic potential energy

New GCSE AQA Physics lesson on ‘Gravitational potential energy, kinetic energy, and elastic energy’ written in line with new AQA Physics specification.

Starter relates the previous lesson on ‘work done’ to the current lesson on energy which also brings in the idea of conservation of energy.

Provided a clear explanation of gravitational energy and how this relates to work done students are given the equation which they can immediately use with the ‘book shelf’ activity. Books each of mass 1 kg are flown across different height shelves where students must then calculate their gravitational potential energy.

The idea of kinetic energy is explored by looking at different size vehicles and their top speeds and what this might mean for their kinetic energy. Following the explanation of the equation the students then complete an activity with different vehicles moving across the screen with their speeds and masses visible for student to calculate the kinetic energy of each.

The Elastic potential energy equation is reviewed and then students are able to apply it with review questions.

The elastic potential energy and kinetic energy equations are reviewed in focus to show how they can be re-arranged to make extension and velocity the subject.

Exam questions are provided as a plenary.

Home work questions are provided for review.

Exam questions are given as a plenary task.

Lesson Objectives:

1. Provide definitions for kinetic energy, gravitational potential energy and elastic potential energy.
2. Apply at least two energy equations to problems successfully.
3. Apply and re-arrange all energy equations to problems.
4. Relate work done to changes in energy stores.
