Accelerated reference frame Unaccelerated (constant velocity) reference frame “Choose your own Adventure” Relativity Concept Map Choose a Reference Frame Special Relativity: Main Concepts Principle of Relativity states that every observer sees the same laws of physics. Speed of light is the same for all observers. Application : GPS satellites use constancy of speed of light to pinpoint your location though distance = (speed of light)*(time) Special Relativity Implies: Time Dilation : Clocks in a moving reference frame run slower compared to clocks in non-moving frames. No Universal Time! No Simultaneity Application : Time travel to the future! Length Contraction : Moving rulers (objects) appear shorter Mass is Energy : E=m c 2 Application

Application : Artificial Gravity Principle of Relativity states that every observer sees the same laws of physics. Speed of light is the same for all observers. General Relativity Implies: Special Relativity ! Special relativity is a special case of general relativity, when the reference frames are not accelerating. Bending of Light in Gravity “Rubber Sheet” Twin Paradox Twin on Earth is not accelerating (special relativity) Twin in spaceship is accelerating (general relativity) Using special relativity, Twin on Earth is older....

    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.
