5.01 - Special Theory of Relativity & Time Dilation

General Relativity: Mass can influence Space and Time * General Relativity focuses on Accelerated Motion
Special Relativity (Light): How constant speed influences Space and Time * Constant Velocity Motion: At constant velocity motion, object would be squeezed and compressed along the direction it was moving * Special Relativity focuses on Constant Velocity Motion
Postulate 1 - **The Principle of Relativity**: Laws of physics are the same for observers in all inertial frames of reference
Postulate 2 - **The Speed of Light Principle**: The speed of light in a vacuum has the same value in all inertial systems *

Time Dilation Explanation

Time Dilation Formula

Time Dilation Example

Therefore, special relativity predicts that moving clocks will run more slowly from the point of view of an observer at rest. * Dilated time is always slower than Proper time
