Creating a Top

Wow! It is already December and we are working on rotation in class! Last year, this unit was one of the worst for me because I truly did not understand any of the concepts. I have started to figure out some of the equations and concepts but, I am going to have to work hard all this week in order to really understand the unit. In class last week, Mr. Fullerton gave us a challenge to solve. He gave us a pencil, two small paper plates and six pennies. Our task was to make a top that would spi

Cell Phones

Something I have always wondered is the way in which a cell phone works. Everyone has them in today's world so now I need an explanation to how they work in a physics sense. From what I understand, when someone talks into the phone, their voice is converted into a signal that is transmitted through waves and then back into sound on the other end. Essentially it sounds like a two way radio. The signal is a type of radio wave that in the end can be dangerous to humans resulting in variou

Buoyancy

Buoyancy is the upward force that is exerted opposite to gravity with a liquid. In the diagram below, buoyancy is shown acting against gravity keeping up with the laws of Sir Isaac Newton. Buoyancy is the reasons some objects float on the water and some objects sink. Because it is spring break and I am on vacation by the ocean, I thought it was fitting to look into buoyancy. A rock sinks right to the bottom while boats and kayaks float on top of the water. The video below shows how ext

Clean games equal good scores and good scores equal a happy Rachel. (Clean games are games with all strikes and spares) For the past 6 years now, I have bowled for the school and on weekends, I participated in a league to improve. Every season has its ups and downs and currently, I am in a hole that I can

A Box of Minions

At the start, many of the yellow minions with cool goggles and a few strands of hair were captured by the evil Gru. Gru did not want them anymore so he decided to throw them all into a box to ship them off to an island in the middle of nowhere. Gru pushed the box at a constant speed along the ground that had friction. Once he got to the car, he realized that he would have to lift the box with a certain force. The work that Gru does is equal to the negative change in potential energy. He then fli
