Einstein’s Relativity — Space, Time & Motion Explained | Chapter 37 of University Physics Chapter 37 introduces the revolutionary ideas of Einstein’s relativity, showing how observers in different frames perceive space and time, and how mass and energy are intertwined. From time dilation to the curvature of spacetime in gravity, these concepts reshape our understanding of the universe. Watch the full video summary here for clear visual explanations of relativity in action. Special Relativity: Postulates & Key Effects Einstein’s two postulates underpin special relativity: Principle of Relativity: Laws of physics are identical in all inertial frames. Constancy of Light Speed: Light travels at c in vacuum for all observers. Consequences include: Relativity of Simultaneity: Events simultaneous in one frame may not be in another. Time Dilation: Moving clocks tick slower: Δt = γ Δt₀. Length Contraction: Moving objects shorten: L = L₀/γ. Lorentz T...
