1. Consequences of Special Relativity

2. Let’s Recap!

3. What is Special Relativity Theory? Special Relativity Theory is a theory which predicts how events are measured with various observers who are in motion with respect to an event.

4. Postulates of the Special Relativity Consistent Law Principle- The laws of physics are the same in all frames of reference that are moving at a constant velocity with respect to one another.

5. Postulates of the Special Relativity Constancy of Speed- The speed of light in an empty space has the same magnitude for all observers regardless of their velocity.

6. 5 Key Concepts of Special Relativity

7. 5 Key Concepts of Special Relativity Relativity of Simultaneity Time Dilation Length Contraction Mass-Energy Equivalence Cosmic Speed Limit

8. 1. Relativity of Simultaneity If two events are separated in space or position, it is absolutely impossible for the two events to occur simultaneously for two observers.

9. 1. Relativity of Simultaneity An event is only simultaneous for an observer, but not necessarily simultaneous for another observer.

10. 2. Time Dilation The faster you move through space, the slower one moves through time

11. 2. Time Dilation Occurs due to a relative velocity and difference in gravitational field.

12. 3. Length Contraction An observer at rest would observe a moving object’s length to be shorter than its proper length.

13. 4. Mass-Energy Equivalence Anything that has a mass has an equal amount of energy. E=mc^2

14. 4. Mass-Energy Equivalence Everything that has mass, even those at rest, have inherent energies.

15. 4. Mass-Energy Equivalence C can never be attained or surpassed by any massive object.

16. 5. Cosmic Speed Limit c= 300,000,000 m/s

17. 5. Cosmic Speed Limit As object travels faster, the more massive it needs to be. As objects become more massive, more energy will be required for it to move faster.
