HG-1 THE HEAT OF FUSION OF ICE Introduction When heat flows into a system there are a number of things that can happen. One result could be a temperature rise. Or‚ the system might even catch fire. A third possibility is a change of state. As you know‚ matter exists in three states (or maybe four‚ the fourth being a plasma)‚ solid‚ liquid and gaseous. At different temperatures‚ the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In solids

through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill‚ gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the track. The law of physics is basically the engine of the train. At the top of the hill‚ the cars possess

Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique

Report on “Physics of the Impossible” by Michio Kaku The most recent book that I have read is “Physics of the Impossible” written by Michio Kaku. It seems like the author doesn’t know the meaning of the word “impossible”‚ or rather‚ to be slightly more accurate‚ he has redefined the term to enable him realistically to examine and predict the future of science and technologies‚ from teleportation and time travel to robots and starships. Michio Kaku is an esteemed theoretical physicist and one of

TAP 601-1: Brownian motion Brownian motion (named after the botanist Robert Brown) is the presumably random drifting of particles suspended in a fluid (a liquid or a gas) or the mathematical model used to describe such random movements‚ which is often called a particle theory. The experiment of Brownian motion in a smoke cell is a classic experiment that gives strong circumstantial evidence for the particulate nature of air.

people fail to realize the importance of physics in athletics. People who are untrained in the scientific field may believe that an athlete’s performance level is solely based on their skill-set‚ such as strength and training. However‚ one’s ability to employ physics concepts is the true determinant for success. This is imperative to dancers; most movement and technique can be improved dramatically by following Newton’s laws accordingly. By utilizing key physics concepts‚ a dancer can improve by locating
