Hi everyone,
I have often wondered about the time and distance relationship.
Case in point: If you wind a flat coil, let's say six inches in diameter, and cause a current to run though it. The electrons that travel on the outer most perimeter will need to travel a much longer distance to complete one circumference compared to the inner most electrons to complete one distance around. I understand that each electron will travel the same speed but cover a different distance because the wire is of one piece. This alone took me months to understand. This is much like the hands on a clock. It's now obvious, to me, that the inner part of the hour hand will spend the same amount of time completing one revoluation. What is so confusing to me is that, when a person is holding a rope and two objects are attached at different distances away on that rope and then spun so that the stones are now air borne, the objects are read to be traveling at different speeds according to a radar detector? How is this discrepancy justified? For me this is much like walking with the moon as it rotates around our Earth. A traveler would take 24hrs. to complete one trip around our planet, which would be X amount of time over the distance but the moon also travels within the same time frame. Would the moon be traveling the same speed as the traveler on Earth? I would say not.
Thanks for all your input
