### 1. Mass and Energy: Description and Interchangeable Relationship

Einstein used E = mc^2 to prove that mass and energy are relative to each other. This lesson describes how energy can be converted into mass and mass into energy. Experimental results from particle accelerators are used to demonstrate the relative nature of mass and energy.

### 2. General and Special Relativity: Theory and Examples

Special relativity accounts for the constant speed of light in the absence of surrounding mass. General relativity utilizes the concept of space-time to explain the effect of gravity on the speed of light. This lesson compares special and general relativity and provides examples of how the speed of light is affected by gravity.

### 3. The Law of Conservation of Mass: Definition, Equation & Examples

Read about the law of conservation of mass, its role in chemistry, and its importance in the universe. Learn the equation, review examples, and test your knowledge of the material with a short quiz.
