Special Relativity $100 Answer Back to Jeopardy What are the two postulates of special relativity? The Laws of physics apply in all inertial frames of reference. There is no preferred frame. The speed of light in a vacuum is constant for all frames.

Special Relativity $200 Answer Back to Jeopardy Einstein's famous equation E O = m O c 2 is a statement of The equivalence of mass and energy E O = rest energy m O is called rest mass.

Special Relativity $300 Answer Back to Jeopardy Time dilation is the prediction of special relativity that moving clocks run slow.

Special Relativity $400 Answer Back to Jeopardy The prediction from special relativity that the length of a moving object will be shortened in the direction of motion is called length contraction.

v approaches c $100 Answer Back to Jeopardy According to special relativity the kinetic energy of a moving object is equal to.

v approaches c $200 Answer Back to Jeopardy Because of their short lifetimes, very few muons that are produced in the upper atmosphere at high speeds should be observed at the surface of the earth. Yet we detect large numbers of muons at ground level because of the special relativistic effect of time dilation.

v approaches c $300 Answer Back to Jeopardy What happens as object approaches the speed of light? Mass increases Length contracts Time Slows down

v approaches c $400 Answer Back to Jeopardy What is the formula for length contraction? L Rel = Lo*(1- (v/c)²) 0.5

Matter & Antimatter $100 Answer Back to Jeopardy An electron and a positron, which are two massive particles, can annihilate when they come together to produce two photons, which have no mass. According to special relativity, this pair annihilation is an example of the equivalence of mass and energy.

Matter & Antimatter $200 Answer Back to Jeopardy When it comes near a heavy nucleus, a gamma ray, which is a high energy photon, can "disappear," and in its place there will be produced an electron and a positron, which both have mass. According to special relativity, this pair production is an example the equivalence of mass and energy
