PHYS 1010 Notes Week 11 March 30 April 1 Relativity of length Length of moving objects is relative As an object moves, length contracts Moving at the speed of light > length is 0 Relativity of momentum Mass increases the faster you go Moving at the speed of light: infinite mass requires infinite force Relativity of energy Mass and energy are the same thing (mass is the physical representation of potential energy) Manhattan Project: development project of nuclear weapons Mass > energy Trinity Test: detonation of plutonium bomb Proved Einstein’s theory of relativity Radiation Mass turning into energy in unstable atoms Nuclear fission: breaking big things apart; how we generate nuclear power Leaves nuclear waste Nuclear fusion: taking small atoms and ramming them together; give off energy because they lose a little mass No waste, no toxicity Takes too much energy (takes more energy to complete process than we get out of it) Light turning into an electron Turns into two particles > electron and positron (electron with + charge) Electrons are matter Positrons are antimatter Electrons smashing into positrons destroy each other and turn into light
