If somebody wants to complain that there is uncertainty related to the masses, we can see from the collision that there is a clear mass difference (we know what happens with equal masses). As both objects leave roughly with 1V, we know we have witnessed the miracle of free momentum.
I really don't think you or other people should be adopting Inmendham's false semantics, even as a joke. It only confuses other people who might not understand the entire debate. In my opinion, when you or Ian or Dispar say "free momentum" you only fall under his semantic trap. Take my message however you wish.
Its a shame that other certain individuals out there, dont aquire bigger balls! Awesome work Ian, very nice clear demo, thank you for going to the bitter end on this one mate and thanks for sharing. While this looks simple, i fully appreciate the time and effort you have put into it, the scrubbing of the permanent marker off the board sounds like a massive ball ache alone. If you are in need of digital scales they are really quite cheap off ebay, the set I bought only go up to a maximum of 500g and were less than £4, Im happy to send some links if your interested mate.👍😊
I think it'sworth re-uploading the experiment you mentioned and a few othres, maybe title them so that they come up in searches better, unless the titles are already as good as they can be - I made the mistake of titling things with reference to Goofy, which no-one's gonna be searching for, so when I wanted to find certain videos of my own, I often couldnt even find my own videos on certain topics, so good luck anyone else finding them lol! Not that I care that much - it was only really ever about trying to rationalise with Goofy and his multi-named fan. Playlists are helpful as well but you might have already organised your content into playlists. No idea what he's arguing about these days but it's bound to be yet more pseudo scientific rubbish so I don't waste my time listening to him drone on repetitively any more - it's not like one day he's gonna say something new and interesting or valid.
After the first bounce the momentum of the large ball equals 1.5 times the incoming momentum. (p = mv) (3 × mass1) × ½ v1 The small ball has 0.5 times the initial momentum. (mass1) × ½ v1 Velocities: v'1 = v1 × (m1 - m2)/(m1 + m2) v'2 = v1 × (2 × m1)/(m1 + m2) If m2 > m1 then v'1 is in the opposite direction, and therefore the momentum will also be in the opposite direction. (p'2 - p'1 = p1)
@@Ian.Gostling You could twist a short piece of copper wire firmly around the top of the larger ball though. And experiment a bit with the correct length.
@@Ian.Gostling Yes, you take two inch of magnet wire, and twist it around the top of the ball with your pliers, to make the ball weigh triple the small ball. You can calculate the exact length of the wire, or clip it to the experimental length.
