Nice demo of an analog computer today. the first oscilloscope has a circle which is being generated by one section of the analog computer, and is brought out for illustration on that scope.
On another scope you will see the ball bouncing with gravity decay (it peters out and roles by the time it is across the display.
Another part of the analog computer is generating the horizontal (right to left sweep) the vertical (being bounced in the air, the petering out) and a delay which is subtle at the start or right side when the ball reappears.
Pretty complicated and nice stuff. All of this sort of technology can have other independent inputs to the analog computer which changes any of this. The rate of the ball going up to start with, how high it goes, how fast the bounce displays, and how fast it is moving.
Think this sort of thing applied to say a missile or such, this is the technology that was used, and sometimes is still used, though it is not uncommon for this to all be digitally simulated to work just like this system does.
