And none of this has anything to do with the rotational forces at work ina wheel.
Others understood the comparison.
To make it clearer for you:
Drop a solid steel ball the diameter of a ping-pong ball from a height of 12 inches into a bathtub filled with water to a depth of about 10 inches.
Observe the behavior of the steel ball. Does it bounce from the water surface? If not, how rapidly does it descend in the water?
Do the same with a ping-pong ball. Does it descend as rapidly as the steel ball? Why not?
And: why quotation marks for "container"?
Those words are spelled "gravity" and "buoyancy," by the way.
