Course overview
Learners will be taught on a rota on the following topics;
Particle model of matter & internal energy; In this unit learners will recap the different states of matter. They will look into why temperature remains the same when there is a change in state. They will look at density and have an opportunity to complete the required practical to measure the density of regular and irregular shapes. Learners then look at heat transfer and the specific heat capacity of different materials.
Motors and generators; Magnetism and electromagnetism recap. Learners need to recall the basic concepts of magnetism and electromagnetism previously taught in KS4. Learners must understand the motor effect and how this can be applied to both electric motors and loudspeaker units. Learners cover the generator effect and how this can be applied to microphones. The concept of electromagnetic induction is introduced. Learners recall AC and DC and learn to differentiate between the outputs of alternators and dynamos. Practical uses are covered. The workings of the National Grid is taught in the context of step up and step down transformers combined with methods used to calculate potential difference changes.
Key Concept:
