Work - A level Physics (OCR A)

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 7) Energy stores and energy transfers 8) Derivation of gravitational potential energy and kinetic energy 10) Principle of conservation of energy 11) Energy transfer between kinetic and GPE (including possible practical) 13) The definitions for thinking, braking and stopping distances 14) Graphical representations of thinking/braking distance 17) Factors affecting stopping distance 18) The definition of power and the watt 22) Derivation of power equation in terms of force and velocity 24) The meaning of efficiency 25) Equations for efficiency 27) 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.
