I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

Objectives: • To be able to explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results. • To study the effect of intensity of light on photoelectric experiment. • To estimate the Planck’s constant‚ h through the simulation. • To be determine how to calculate the wavelength of light‚ the work function of the metal‚ or the stopping potential‚ if given the other two. Beginning with the plate made of sodium. Keep all the parameters

Components of Force Vectors Equipment: String‚ spring scales‚ 1.00 kg hooked mass‚ supports‚ meter stick‚ protractor‚ 20-N spring scales. Objective: During this lab‚ you will investigate the relationship between the angle of an applied force and the magnitude of one component. You will compare your actual force with the theoretical force and provide a computer generated data table that calculates the theoretical values. You will graph your actual and theoretical values and provide a complete

Introduction of Physics: Physics ("knowledge of nature") is the science concerned with the discovery and understanding of the most basic fundamental laws of the universe that control the way everything in the world around us behaves. Discoveries in basic physics have important ramifications for all of science. Physics attempts to describe the natural world by the application of logic scientific methods‚ including modeling by theoreticians. As a core scientific discipline‚ physics is concerned with

Student Project The Physics of Sports Instructions: One of the best (and most fun) ways to explore physics and how it relates to the real-world is through sports. Every sport utilizes multiple physics principles. For this project you will chose a sport and study the physics principles involved. The sport you choose must be an actual sport‚ not a computer simulation or animation You will create a short PowerPoint presentation (5 slides max) summarizing your project. The following outline is designed

Physics End of Year Reflection Paper At the beginning of this course you were given some overarching enduring understandings and essential questions. These were: Overarching Enduring Understandings: Students will uncover and use appropriate scientific models to describe and quantify the nature and interactions of matter and energy. Students should understand that there is a network of rules and relationships that determine what will happen in a given situation Students

The sport of tennis has multiple opportunities in which the study of physics can go in depth. The sport’s court‚ racquet‚ ball‚ and even the player contain unlimited amounts of physics in which a person can go more into detail with as they study. While it is true that these all contain some form of physics‚ the racquet and how it interacts with the ball is where most of the physics is apparent. Starting with the racquet a person is able to see four main areas of focus. These focuses consist of the

Cosmology By: Jarrett Leuta-Douyere A New Look at Sports Growing up in a family filled with athletic desire to be great at whatever sport we would participate in and understanding simple physics in Cosmetology‚ I never realized how much physics comes into play when playing sports. We don’t call it physics when were playing‚ football‚ basketball‚ baseball because it’s just a natural feeling when were throwing a ball or trying to tackle someone. When we began to learn about Newton’s law of Gravity
