Students Will Review

This chapter helps students review the concepts in a classical relativity unit of a standard college physics course. Topics covered include:

  • Time and distance as relative concepts depending on the observer
  • Using light to demonstrate how classical relativity works
  • Clarification of time dilation and real-world examples
  • The phenomenon of space contraction with faster moving objects
  • The interchangeable relationship of energy and mass
  • Different examples and theories of both special and general relativity

Classical Relativity: Distance and Time Relation to the Observer

1. Classical Relativity: Distance and Time Relation to the Observer

Classical relativity is used to explain how speed is relative to the state of motion of an object and the observer. Explore classical relativity, distance and time, speed and motion, and discover a complex example of classical relativity and the exception to the rule.

Light and Relativity: Breakdown of Classical Relativity with Light Example

2. Light and Relativity: Breakdown of Classical Relativity with Light Example

The relativity of distance and time accounts for the constant speed of light. Explore the theory of relativity, classical relativity and an example, discover if motion and speed are relative, and learn about relativity at high speeds and how light speed can be constant.

Time Dilation: Description, Explanation & Examples

3. Time Dilation: Description, Explanation & Examples

Time is a relative concept and speed causes time to go slower. Learn about time dilation, including its description and explanation. Explore examples to understand that while time dilation is relative, the speed of light is not.

Space Contraction: Shortening Distance for Fast Moving Objects

4. Space Contraction: Shortening Distance for Fast Moving Objects

Space contraction refers to the process of distance becoming shorter for fast moving objects. Explore this process and learn about length contraction and the speed of light.

Mass and Energy: Description and Interchangeable Relationship

5. Mass and Energy: Description and Interchangeable Relationship

Einstein's theory of relativity proved that mass and energy are relative. Explore Einstein's theory, his descriptions and evidence for the relativity of mass and energy, and learn about this interchangeable relationship of mass to energy and energy to mass.

General and Special Relativity: Theory and Examples

6. General and Special Relativity: Theory and Examples

The speed of light is affected by both general and special relativity. Learn about the theories and consider examples of general and special relativity. Explore gravity and space-time in the context of general and special relativity.
