When I was in ninth grade, my vision rapidly started to deteriorate. I went from perfect vision to not being able to read simple words more than 15 feet away.
Glasses can be used to look at a few topics in physics, the first (and easiest) being how they stay on my nose. The force of friction between my nose and the glasses overcomes the force of gravity trying to pull my glasses of my face, and when they slide down my nose, the force of gravity is higher than the force of friction and so t
One thing I do on a daily basis is drop things. For example, pieces of paper or folders. When these things fall, they have the force of mg down, and the force of air resistance up. The paper will reach a terminal velocity and continue to fall at this velocity until it hits the ground. The force that the paper exerts on the floor is equal to the force the floor exerts on the paper. The coefficient of friction between the tile floor and the paper is likely small because the tile is smooth and the
I recently got an 8 week old kitten on September 20th and have been spending all my time watching her and keeping her out of trouble (not only has she stepped on my keyboard an uncountable amount of times while I wrote this, she also deleted the whole thing twice). I figured I'd kill two birds with one stone and do some physics with her in mind.
She often jumps off of my bed, so I figured I'd find her final velocity the instant before she hits the ground. I know her vertical acceleration du
Our class was given the task to collaborate on a lab to find the distance a ball would go when fired and place a target where we believed it would land. The class was allowed to fire the ball once, then the ball would be moved and the angle would change. Together, we took measurements of the first setup, and started doing calculations. We worked in small groups and compared answers, coming to a conclusion that the initial velocity of the ball was around 4.65 m/s. This allowed us to start to calc
Overall, I have been enjoying the first few days of physics class and reviewing the content we learned last year. It was generally pretty easy. However, let me talk about scientific notation. I thought I was good at it before this year, but I guess not. I read the first chapter of the textbook and watched the first lecture and figured I was well prepared to start the intro WebAssign. For some reason, the scientific notation problems gave me the most trouble. I re-read the chapter, and figured I'
