The principle of constancy of the speed of Light in free-space
... the STR in explaining and predicting experimental facts and its internal consistency give an indirect proof of its two postulates. Thus it is essential to insist that such a fundamental idea as the invariance of the speed of light in vacuum should be derivable from the simple and more basic assumpti ...

Motion Along a Straight Line at Constant
... In exactly the same way as we can connect force f and acceleration a using Newton’s 2nd law of motion, we can arrive at the centripetal force which is keeping the object moving in a circle ...
