Conservación de la energía y formas de energía: almacenes y transferencias

Notes

energy stores law of conservation - energy cannot be created or destroyed energy can only be transferred from one energy store to another or from one system to another. System - energy moves between different things. energy moves from one system to another means = energy moves from one thing -> another thing. a store = where energy sits a frantic = how energy moves energy is either 4 ways energy moves - mechanically -> energy moves by force or movement kicking a ball electrically -> Energy moves through wires Charger -> phone healing -> energy moves from hot -> cold hot tea warming your hands radiation -> energy moves by waves Sunlight / sound thermal -> something is hot : you turn on a kettle -> main gets hot kinetic -> something is moving : a car driving gravitational -> something is high up : you hold a book in the air chemical -> energy in food, fuel, batteries : you run food, your body gets energy elastic -> stretched or squashed things : pull a rubber band -> it stores energy -> let go = snaps magnetic -> magnets pushing / pulling : push two magnets together electrostatic = electric charges = rub a balloon on hair nuclear -> ...
