Chapter 26 Notes College Physics by Giambattista et al. John B. Ross, Ph.D. IUPUI Physics Dept. Special Relativity Mechanics – theory of motion, relative velocities add as vectors E/M – charges make fields, e/m waves travel at c in vacuum Postulate 1: Laws of physics are the same in all inertial reference frames. Inertial frames do not accelerate; they are at rest or moving at constant velocity. What is the speed of the ball relative to the ground? 90 mph 50 mph What is the speed of the laser beam relative to the ground? c 0.5 c Postulate 2: Speed of light in a vacuum is the same in all inertial ref frames. Which beam hits first? c c 0.5 c Outcomes of Special Theory: Time dilation Δ

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
