Q1. Figure out how quick a GPS satellite is moving relative to somebody on the ground and from that how much slower time runs where it is in orbit relative to somebody on the ground.
Q2. Assess the overall ratio of clock time on a satellite to clock time on the earth. In specific, if you are on earth and 1 second passes on an earth clock, how much time passes on the satellite clock?
Q3. If one encompasses two clocks at ‘infinity’ and ensure that they run the same, and then lets one drop, then at what speed will the falling one encompass as it reaches the ground relative to the one at infinity?
Q4. Use those outcomes to estimate how much slower a clock goes close to the earth than one, which is higher up. (Put in the speed from problem 3 to the special relativistic time dilation formula. Here we use the word ‘estimate’ since the true answer is in fact a little different, however to get that would take much more math than we wish for to use here!)
