Energy is a number you can work out for a situation, and the discovery is that the number never changes. Everything else in this unit follows from that.
- 03Conservation of energyModelA pendulum comes back almost as high, but only almost, and after a few hundred swings it hangs straight down. What happened to its energy?Open this lesson
- 04Heating and thermal equilibriumModelA sparkler throws sparks at 1500 °C and they barely sting. A bath at 40 °C makes you flinch. How can that be?Open this lesson
- 05ConductionProcessA metal spoon and a wooden spoon have been in the same drawer all night. The metal one feels distinctly colder. Which one is colder?Open this lesson
- 06RadiationProcessConduction needs particles touching. Convection needs a fluid that can move. Between here and the Sun there is neither — and yet you can feel sunlight on your face.Open this lesson
- 07InsulationInvestigationTwo identical ice cubes. One in the open air, one wrapped in a thick woollen blanket — the sort you would call warm. Which melts first?Open this lesson
- 08Simple machinesQuantitativeA paving slab weighing 600 N will not budge. Slide a crowbar underneath and a push of 100 N lifts it. The bar has no motor and no battery. Where did the extra 500 N come from?Open this lesson
