College

Physics was pretty epic! The trebuchet worked and worked very well. but some of the tests had some very weird results.

For example:
When it was set up with a 2 kilo counterweight and a 100g throw ball at a 70:15 arm ratio, it threw around about 4m each time, but when it was changed to a 75:10 arm ration it threw the ball backwards... strange.

And the total range for it on a 2 kilo to 100g ball was about 6-7m which is actually pretty good, I think.

But on the downside, I was told today that a massive bit of geology is due in in 2 days time, and I haven't even started it yet!!! Looks like tonight is not going to be spent youtubing and making new videos but more looking at the geology of aquifers... fun fun fun!
