Compléter Writing Theory Of RelativityVersion en ligne Complete the next text according to the missing words par Maleja Jimenez Castellanos 1 symbol moving speed spaceships Einstein's speed astronaut between objects theory going physics observations speed explains relative principles respect absolute Einstein explained that when two objects are at a constant as the motion the two , instead of appealing to the ether as an frame of reference that defined what was on . If you and some , Amber , are moving in different and want to compare your , all that matters is how fast you and Amber are moving with to each other . Special relativity includes only the special case ( hence the name ) where the motion is uniform . The motion it is only if you're traveling in a straight line at a constant speed . As soon as you accelerate or curve ? or do anything that changes the nature of the motion in any way ? special relativity ceases to apply . That's where general of relativity comes in , because it can explain the general case of any sort of motion . Einstein's theory was based on two key : The principle of relativity : The laws of don't change , even for objects moving in inertial ( constant ) frames of reference . The principle of the of light : The speed of light is the same for all observers , regardless of their motion relative to the light source . ( Physicists write this speed using the c . )
