I already talked about raking so I decided to do a short thing about what causes the leaves to fall onto the ground in the first place, which is a mix of chemistry and physics. I am not so sure about the chemical part but the leaves turn colors for some reason and they die, and fall of the trees for reasons I don't know, but the physics is somewhat more manageable. If we set up a free body diagram for the leaf on the tree, there would be mass times gravity pulling down, while tension is going up
So today I had to rake my whole frontyard and there were plenty of leaves to deal with thanks to Sandy, but doing the mindnumbing work that wastes my Saturday, I pondered the physics of the job. While raking, I make an arching swing with the rake, hitting the leaves at the lowest point of my swing, and continuing the swing, putting the rake head sort of into a form of uniform circular motion. While in the motion, I pick up the leaves and they join the rake head on its path until they fall off, a
I made the U in trebuchet a capital because every time David says it he says it wrong so this thing shows how I feel ->:banghead)
But on a physics note, after we fired our trebuchet I was wondering how fast the softball went and how we could have improved the firing. So our maximum distance was 38 yards which I'm and just going to say is 38 meters, and to go this distance if was in the air for 2.55 seconds. With this we can find that the initial velocity of the ball in the x-direction would
So it felt like a good time to write a second blog so here I am. Writing the second blog. Well we just got back that test on dynamics I think and I got an 8 out of 20 so thats not too good. Slim Shady tells us not to worry about the grade but I don't know how to do that if it's a big part of our grades. I guess the thing that I'm not too good at is making all the algebraic connections we have to make to get from one equation to the other and to solve for all the things we want to find out. And o
So I'm kind of cutting close here with this blog post starting it at 11:30 on Friday night but I'm not worried. I guess that from this you could gather that I am a little bit disorganized and I procrastinate a little bit but other that I am a hard worker. I like physics a ton and hope to become an engineer of sorts when I get older, but I'm not sure what type yet. I love to play soccer and we finally won our first game tonight and I expect many more to come. In terms of physics, I'm taking AP-C
