Einstein's Special Theory of Relativity | 1. 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. |
Inertial Frame | - at a constant velocity or at rest - does not experience acceleration - no experiment to determine who is stationary |
Addition of Velocities | Velocities are not arithmetically additive. - two people observing the same object will see different velocities. |
Time | As speed approaches the speed of light, time dilates: their clock appears to run slow. |
Length | As speed approaches the speed of light length contracts in the direction of motion. |
Mass/Momentum | As speed approaches the speed of light mass increases exponentially. Momentum must be conserved. |
Colour | As speed approaches the speed of light the colour changes due to the Doppler Shift/Effect. |
Energy | E = m\(c^2\)\(\gamma\) |
Time and Mass | |
Length | |
Momentum | |
Simultaneity | - simultaneous events only occur simultaneously in certain frames of reference - the sequence is different for the moving frame |
Luminiferous Aether | Light bearing aether - what they used to think light travelled through - thought that waves needed a medium to travel through |
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 |
