      ⓘ Dogs don't have thumbs Retweeted Robert Kroese

      Imagine swinging a rock over your head in a circle, on a string. Add more energy, and the rock speeds up. Now replace the string w a bungee cord. Add more energy, and the cord stretches / the rock moves further out. The energy is stored in cord. Gravity is that bungee cord.https://twitter.com/robkroese/status/1048712341527953409 …

      I'm confused by this: "Once the two spacecraft are sufficiently close, the chaser's orbit is synchronized with the target's orbit. That is, the chaser will be accelerated. This increase in velocity carries the chaser to a higher orbit." 1/ https://en.m.wikipedia.org/wiki/Space_rendezvous …

      2/ Analogy isn't perfect, bc the dF/dz for gravity has a downward slope, but the dF/dz for a bungee cord INCREASES, but it's a hand-waving way to see that the energy is soaked up by increasing the radius, not the velocity

      3/ Here's yet another way to look at it. Picture that big funnel with a steel ball bearing you see at science museums. Release the ball on a tangential path. It circles the funnel, WAYYY out at the lip, slowly, slowly. Yes? That ball has a LOT of potential energy right now. >

          4/ Keep going. More air resistance, ball drops lower, ball goes FASTER. Yet more. Yet lower. Yet faster. Agreed? Videotape that...and play it backwards.

          5/ Now, in addition to the backwards masking where the prog rock soundtrack turns into Geroge Soros asking you to destroy western civilization through big government, what ELSE is going on?

          6/ Answer: we see a ball orbiting VERY quickly close to the bottom of the funnel, and we see energy being added to it (negative air resistance, but imagine a very tiny rocket). And what happens? It slowly climbs further out, slows down, and stockpiles energy as potential energy.
