Re: SuitSat Tracking



Another way to think about it is to consider what happens when 2 cars go 
around a curve, one on the inside lane and one on the outside lane.  Even if 
traveling at the SAME speed, the car on the inside will be ahead coming out 
of the curve because it didn't have to travel as far as the car on the 
outside (longer radius equals a longer arc subtended)  That's why race car 
drivers always want the inside of a turn!  Then, on top of the effects of 
simple geometry, the pull of gravity adds a component of acceleration, so 
SuitSat will actually speed up,  increasing the lead even more.
