Another nice demonstration Ian. And another nice advert for Sainsburys lol. Not sure whether to give you 10/10 or mark you down a bit for your singing. Just kidding - I like to hear someone happy in their work. 10/10.
@@Ian.Gostling It will be the same old same old after tomorrow, rich get richer and poor get poorer, that's how the establishment has run the country since the Victorian era.👍😊
If you're gonna do it properly, measure it. 5 or 10 drops with the 4 weight at 1 height, 5 or 10 drops with the 1 weight at 1 height, 5 or 10 drops with the 1 weight at 2 height. Measure the washer height from surface, a ruler should be accurate enough, drop the lowest and highest of each group and average the rest. It won't prove anything more than you're already proving, but it makes for a bulletproof argument. Not sure we're allowed to mention bullets when we're talking about mv^2, though.
