Relativity
Cards in this deck (14)
- 1Einstein's Special Theory of Relativity1. The laws of physics are the same for all objects moving in the same frame of reference at a constant velocity.
2. The free space velocity of light is constant for all observers, regardless of their state of motion. - 2Inertial Frame- at a constant velocity or at rest
- does not experience acceleration
- no experiment to determine who is stationary - 3Addition of VelocitiesVelocities are not arithmetically additive.
- two people observing the same object will see different velocities. - 4TimeAs speed approaches the speed of light, time dilates: their clock appears to run slow.
- 5LengthAs speed approaches the speed of light length contracts in the direction of motion.
- 6Mass/MomentumAs speed approaches the speed of light mass increases exponentially.
Momentum must be conserved. - 7ColourAs speed approaches the speed of light the colour changes due to the Doppler Shift/Effect.
- 8EnergyE = m\(c^2\)\(\gamma\)
- 9—Time and Mass
- 10—Length
- 11—Momentum
- 12Simultaneity- simultaneous events only occur simultaneously in certain frames of reference
- the sequence is different for the moving frame - 13Luminiferous AetherLight bearing aether
- what they used to think light travelled through
- thought that waves needed a medium to travel through - 14—Michaelson-Morley Experiment (1887)
- to test for Luminiferous Aether
- two beams of light travel in different planes
- there should be a refraction pattern due to time difference
- the experiment was a failure
