Consequences of Einstein's Relativity Chapter 17 3 April 2013 Jeff Ulrich and Joel Hlavaty
Overview • Newton's Laws • Einstein's Postulates and the Implications • Relativistic Doppler Effect • Mass-Energy Equivalence • Twin Paradox • Coexistence/Simultaneity Newton Einstein Doppler E=mc2 Twin Co-exist
Newton's Laws • Rest stays at rest, motion stays in motion • F = ma • Equal and opposite reaction Newton Einstein Doppler E=mc2 Twin Co-exist
Einstein's Postulates Laws of Physics Speed of Light same in all inertial frames constant for all observers, regardless of speed of source 1. 2. Newton Einstein Doppler E=mc2 Twin Co-exist
Implications of Einstein's Postulates • Relativistic Doppler Effect • Mass-Energy Equivalence • Twin "Paradox" • Coexistence/Simultaneity Newton Einstein Doppler E=mc2 Twin Co-exist
Relativistic Doppler Effect • observer and source • passing car • observed frequency altered • actual velocity is constant big bang theory- 45s Newton Einstein Doppler E=mc2 Twin Co-exist
Mass-Energy Equivalence : energy relative to observer Application of Lorentz to electromagnetics: Newton Einstein Doppler E=mc2 Twin Co-exist
Mass-Energy Equivalence minute physics (14s) Newton Einstein Doppler E=mc2 Twin Co-exist
Twin Paradox video Newton Einstein Doppler E=mc2 Twin Co-exist
Twin Paradox video Newton Einstein Doppler E=mc2 Twin Co-exist
Twin Paradox video Newton Einstein Doppler E=mc2 Twin Co-exist
Twin Paradox -Not both in inertial frames! -Accelerations during turnaround video Newton Einstein Doppler E=mc2 Twin Co-exist
Coexistence & Simultaneity -Different observed times depending on inertial frame lightning train minute physics moving cart Newton Einstein Doppler E=mc2 Twin Co-exist
