If time is relative, is speed also?

Question

If we measure time by the solar year, would we calculate speed on another planet, like mars maybe, differently based on it’s solar year? Or would we use “Earth speed”?

Answer 1

A solar year is a solar year whether you are on Earth or Mars. It takes the same amount of time. What changes is that on Mars it takes longer for the planet to orbit around the sun. But if you lived on Mars you’d still age at the same rate.

Speed is the same, whether you measure in kilometers per hour or miles per second, you are still going the same speed, just the units you use change. So yes you could change units based on a martian year vs. an earth year, but a kilometer is still a kilometer, a mile is still a mile.

Time becomes relative when you are talking about traveling at super high speeds and experiencing relativistic effects, but thats only compared to another frame of reference. If you are on a planet traveling .99999 the speed of light relative to earth, you will experience the same distance and time on YOUR planet because thats the frame of reference you are in.
