Energy & Power - A level Physics (OCR A)

Unit: Energy & Power
Number of lessons: 6

This bundle includes all six lessons in my unit Energy & Power. It is specifically linked to the OCR Physics A Specification, but should apply to most A Level Physics courses.

The lessons cover the following points:

1. The definition of work done
2. Determining scalar/vector natures from equations
3. Joule as the unit of work
4. Definition of the joule
5. Energy stores and energy transfers
6. Derivation of gravitational potential energy and kinetic energy
7. Principle of conservation of energy
8. Energy transfer between kinetic and GPE (including possible practical)
9. The definitions for thinking, braking and stopping distances
10. Graphical representations of thinking/braking distance
11. Factors affecting stopping distance
12. The definition of power and the watt
13. Derivation of power equation in terms of force and velocity
14. The meaning of efficiency
15. Equations for efficiency
16. Loads of questions and problems

There are detailed teacher notes in the ‘Notes’ section of each slide, including answers where required.

My first unit of lessons (Physical Quantities & Units) is available free of charge for you to see the style I employ.
