Document Summary

Electroweak force, weak interaction, electromagnetism, electricity and magnetism: fundamental rules of the game. Electromagnetism, electricity and magnetism: rules, prominent scientists still didn"t yet believe in atoms. Energy: later proved to be the same as mass. Energy is the ability to do work . Energy and conversions: energy in 1g tnt = 1calorie, energy in 1g butter = 8calorie, power = energy/time, or the rate of energy transfer, tnt seems more explosive because the energy is given off all at once. Butter takes longer to give off energy: tnt is more powerful than butter. Unites of energy: electron-volt (ev) which is the electrical energy gained by moving one electron through one volt, a typical chemical reaction at the molecular level absorbs or releases energy in the range of a few ev. 1ev = 3. 829294x10-23c = 1. 602177x10-19j: a typical nuclear reaction involves something on the scale of a few couple hundred mega- electron-volts (mev = 1 million ev)
