1. proportionalEnergy is _____ to mass.

2. relativitythe philosophy that states that all value judgments-- that is, all attempts to distinguish betwee right and wrong-- are relative to the situation (a philosophy which some try to link to relativity)

3. (1.) The speed of light is constant in a vacuum.
and
(2.) The laws of physics are obeyed in an inertial frame of reference.
the two physical absolutes, according to the theory of relativity

4. length contractionterm meaning that, from the perspective of a stationary observer, lengths shorten in the direction (or parallel to the direction) of motion

5. mass, accelerateterm for an object's mass at rest

6. special relativitythe theory which says that all masses produce curves in space, which affect space and time, but not mass

7. etherterm for an object's mass at rest

8. abolute upper limitThe speed of light is a(n) ____ ___ ___ on velocity in the universe.

9. time dilation, length contractionWith respect to an observer's frame of reference, a moving object will experience both ___ ____ and ___ ____.

10. relativismthe philosophy that states that all value judgments-- that is, all attempts to distinguish betwee right and wrong-- are relative to the situation (a philosophy which some try to link to relativity)

11. interferometerthe invisible medium of light that was supposed by nineteenth century scientists to permeate the entire universe

12. Albert A. Michelsonthe American physicist who attempted to find the speed of light through an experiment involving a light source and mirrors on two different mountains

13. the speed of light (c)the American physicist who attempted to find the speed of light through an experiment involving a light source and mirrors on two different mountains

14. general relativitythe theory which says that all masses produce curves in space, which affect space and time, but not mass

15. rest massterm for an object's mass at rest

16. will notthe theory that states how related elements of space and time change with respect to speed or gravity; states that there is no absolute point of reference for physical events

17. time dilationterm meaning that time passes more slowly (takes longer to pass) for the moving clock than the stationary clock, or that from the perspective of a stationary observer, a moving object's clock slows down
