So I did a few more tests today and our best rocket reached its apex at 5.5 seconds. Is that going to be about the max or is there any way to squeeze more time out of it?
This is my sketch.
it is 2 bottles joined together. (Still separated for a 2L compression chamber) It looks almost exactly like that but with a more rounded nosecone.
We did a prelim test today using 30% water which yielded about 5.5 seconds of total flight time from launch to crash. is there any way to find altitude using calculus? I am aware it will be difficult due to the variables but a close guess would suffice.
At the top of the swings motion, you and the swing both enter a free fall state due to gravity and a lack of tension in the chain. Once the tension in the chain is restored and the swing enters circular motion, friction keeps you planted in that seat once again.
I'm currently working on a bottle rocket for my physics class. Instead of taking the assigned experiment, a friend and I have chosen a side experiment to work on.
The experiment: Create a rocket using a 2L bottle as a compression chamber and compare the time required to reach the apex of its...
It was a styrofoam cup so it was insulated pretty well. My guess is my labmates misread or interfered with the final temp by accident. We were looking to find the initial temp of the ice and the lab question was to find the temperature of the physics department's freezer so who knows what went...

I realize that because of gravity and the relatively high density of our place in the universe compared to the voids, cosmologists generally agree expansion isn't really significant, but I don't understand why this is so. If the universe is expanding, then why isn't the space between every atom...
