I love your username, btw. No single character on TV has ever given me greater joy from facial expression alone, than her

If two moving balls hit each other and bounce apart, it’s the exact same thing as if you held the frame steady on one ball and viewed the other ball as moving faster. Just seems like the stationary ball gets heavier…
Perspective is everything.
This link is about the moon but it starts by covering how to view space and orbital objects including simulators which allow one to do what you describe, as well as the ability to move the camera from on ball to the other and many other interesting simulations. https://ciechanow.ski/moon/
Yeah, this one took me a while to wrap my head around and intuitively “get it”. I first learned it was true from that mythbusters episode where they correct their past mistakes… and even they had thought that two cars hitting head on would receive the same energy as hitting a stationary wall at the speed of the sum of their speeds. They were corrected in letters written to them, and then they experimentally verified it.
And even seeing the experimental verification, it still took me a while to really get it. The opposite speeds cancel out, making you go from your speed to zero. Same as if you hit a brick wall at that speed.
Let’s say the two cars are going 50 mph (kph, whatever unit you want). 50-50=0. You experience the same as hitting the brick wall. It’s the difference between initial speed and final speed that matters, not the sum of their speeds.

If you travel due south from Detroit the first foreign country you will hit is Canada.
Takes flight to Detroit Airport, starts heading south: "Canada here I come!"...................................................
That you are now manually blinking, manually breathing and seeing your nose. Do you want to feel your tongue? No? Too bad.
Weird thing as well: your tongue can imagine the texture of any surface. The keyboard? The desk? The mousepad? The toilet brush? You can literally feel it in your tongue!
Probably because when you were a baby you put everything in your mouth, so the data bank is large
