Particle Physics, Special Relativity & Quantum Mechanics - Chapter Summary

This chapter contains a collection of lessons on quantum mechanics, particle physics and special relativity. The standard model of particle physics and the theory of special relativity are just a few of the subjects covered here. Once you complete this chapter, you should be ready to do the following:

  • Outline the four fundamental forces of nature
  • Discuss the ranges and force carriers of the four fundamental forces of nature
  • Define the Bohr model
  • Provide the equation associated with the theory of special relativity
  • Detail special relativity in the natural world
  • Present an overview of the quantum mechanical model
  • Explain the equation used for the Heisenberg uncertainty principle
  • Give examples of the wave-particle duality concept

This chapter takes the stress out of studying even the most challenging of subjects by making them entertaining. Our bite-sized lessons are coupled with self-assessment quizzes to ensure you've understood what you've learned. If you need additional help, our instructors will answer any questions submitted through the Dashboard.

Standard Model of Particle Physics

1. Standard Model of Particle Physics

After completing this lesson, you will be able to explain what the standard model of physics is, name the particles that are part of the standard model, and some of the things it can't currently explain. A short quiz will follow.

The Four Fundamental Forces of Nature

2. The Four Fundamental Forces of Nature

In this lesson, we'll learn about the four fundamental forces of nature. We will define them and then describe some of the surprising ways in which they affect the world around us every day.

Ranges & Force Carriers of the Four Fundamental Forces of Nature

3. Ranges & Force Carriers of the Four Fundamental Forces of Nature

There are four fundamental forces in the universe: gravitational, electromagnetic, weak nuclear and strong nuclear. In this lesson, we will focus on the range of these forces and their force carriers.

Bohr Model: Definition & Equation

4. Bohr Model: Definition & Equation

Explore the problem of the Saturnian atomic model, how the Bohr equation addresses this problem using the hydrogen atom, and what current theory has taken from the Bohr model to refine and improve on it.

Theory of Special Relativity: Definition & Equation

5. Theory of Special Relativity: Definition & Equation

This lesson will go through the main postulates of the special theory of relativity and look at a few of the consequences. The principle equations will also be introduced. A short quiz will follow.

Special Relativity in the Natural World

6. Special Relativity in the Natural World

This lesson will introduce special relativity and its effects in the natural world, using examples to demonstrate how important of a role special relativity plays in the everyday life of our world.

The Quantum Mechanical Model: Definition & Overview

7. The Quantum Mechanical Model: Definition & Overview

Discover the quantum mechanical model of the atom and determine the way in which it is different from the orbital model. Learn about the quantum mechanical properties of electrons, then take a quiz to test what you know.

Heisenberg Uncertainty Principle: Definition & Equation

8. Heisenberg Uncertainty Principle: Definition & Equation

The Heisenberg uncertainty principle is one of the core concepts in quantum mechanics. In this lesson, we define the uncertainty principle and learn more about its implications for physical science.

Wave-Particle Duality: Concept, Explanation & Examples

9. Wave-Particle Duality: Concept, Explanation & Examples

Is light a particle with mass and substance? Or, is it just a wave traveling through space? Most scientists say light is both a particle and a wave! Find out how they came to this strange conclusion as we learn about the theory of wave-particle duality.
