Special Theory of Relativity

Time dilation and length contraction (basic understanding)

1. Introduction to Time Dilation and Length Contraction

  1. These are key concepts in Einstein’s Special Theory of Relativity.
  2. They illustrate the relativity of time and space for observers in different frames of motion.
  3. These phenomena occur at speeds close to the speed of light (c).

Concepts of space and time, mass-energy equivalence (E=mc²)

1. Introduction to Special Relativity

  1. Proposed by Albert Einstein in 1905.
  2. Deals with the physics of objects moving at constant velocity, particularly at speeds close to the speed of light.
  3. Built on two key postulates:
    • The laws of physics are the same in all inertial frames.
    • The speed of light (c) is constant in all inertial frames, regardless of the motion of the source or observer.
