1. Theory of Relativity: Definition & Example
Watch this video lesson, and you will learn about the theory of special relativity and how it applies to you. Learn how you can use one of the most famous equations from this theory to calculate the power inside just one tiny object.
2. Time Dilation: Description, Explanation & Examples
Time slows down for objects in motion. While this effect is not noticeable in everyday experience, it becomes apparent at speeds approaching the speed of light. This lesson defines this phenomenon as time dilation. Examples are used to help explain how time is relative to speed.
3. Space Contraction: Shortening Distance for Fast Moving Objects
The length of a moving object decreases in the same direction it travels. This phenomenon is referred to as space or length contraction. Scientists have proven that space contraction occurs and becomes more prominent at speeds close to the speed of light. This lesson uses examples to explain space contraction and describes how space contraction accounts, in part, for the constant speed of light.
