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

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

The Ballistic Pendulum Crime Lab Physics You are a criminologist‚ and have been given a gun which has been used in the commission of a crime. Both prosecution and defense claim that "muzzle velocity" (speed of the bullet as it leaves the gun) is crucial to the case. Your job...FIND IT! Shown below is a diagram representing a "ballistic pendulum." The bullet is fired into the block‚ the bullet-block combination rises by a height h as shown‚ a little physics is applied‚ and ...voila!...there

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

Philip Pachade AP Physics B Energy Conservation Lab 3/8/2014 Preamble After recently finishing up a take home test on the topics of energy conservation we were given an energy conservation lab for a deeper and more intricate analysis of the law of the conservation of energy. As previously mentioned by many physicists the law of conservation of energy states that energy cannot be created or destroyed‚ but
