Well, two days ago was New Year's Eve, so of course I'm going to write about fireworks. First of all, me and my cousins did fireworks at their house in Waipahu, so there were a lot of those aeriel fireworks, which have projectile motion. Those fireworks need a lot of force from their explosions to propel them up, and since they go so quick it must be faster than gravity can effect them. Not only gravity, but air resistance too. That is why most bottle rockets or whatever are shaped like cones or 3D arrows, know what I'm saying, or else the thing would explode right over someones head. I didn't do any of those fireworks, I stuck to the ground ones, but there was this tank one, where the tank is on wheels and is propelled forward by a flare, which is almost exaclty like the aeriels, except it has to fight friction and it is legal. Overall, I didn't do much fireworks, since I had to get up at 6 the next day...And school starts again in two days, Isn't that great? Go Steelers!!! (hopefully not the last week I'll get to put this on my blog)
Can you guess which ones I took myself and which one I got from Google?
