Guns are a simple idea‚ and work all the better because of it. To put it simply‚ gasses push a projectile out of a barrel. The gun hasn’t changed much since it was created in china centuries ago. Other than looks it has kept the same principle elements‚ the primer‚ the propellant‚ and the projectile (Leghorn). A primer is a small explosive that occurs when the trigger is pulled to light the propellant. Despite what many people think‚ the propellant doesn’t explode‚ it burns. It burns very quickly

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships” (Zitzewitz 1). Ballet cannot be defined

Application Of Physics In Medicine Medical physics is generally speaking the application of physics concepts‚ theories and methods to medicine. A medical physics department may be based in either a hospital or a university. Clinical medical physicists are often found in Diagnostic and Interventional Radiology‚ Nuclear Medicine and Radiation Oncology. However‚ areas of specialty are widely varied in scope and breadth e.g.‚ clinical physiology‚ neurophysiology (Finland)‚ and audiology

Daily Use of Physics Jason L. McDuffy University of Memphis Physics 1 (online) Project 1 Daily Use of Physics Physics is considered to be a powerful lens that helps people view the everyday world. Physics is reflected in the everyday phenomena‚ puzzles and toys that offer a variety of interesting challenges leading to deep and interesting problems that derive from science and mathematics. It provides us an understanding of energy‚ motion and explains these facts as

The Physics of Soccer Tabitha Richeson 1/15/2013 Section 1: overview When I was five I started playing soccer and I loved it. I liked the running‚ the physical aspect of the sport. When playing soccer I didn’t think there was that many rules or science involved but I was wrong. America is the only country to call “soccer” soccer. The rest of the world calls it Football mainly for the reason you use your feet. According to FIFA(International Federation of Association Football) the

How to Excel in Your Physics Course Most students realize that putting off studying until the day before the exam and then cramming at the last minute is not efficient. Some students do this anyway‚ because so far they have gotten away with it. Perhaps most of the other students you previously competed with had poor study skills. This may have allowed you to adopt poor or non-existent study habits and still keep up‚ or even get good grades if you are naturally a better student. Now that you

In 2007‚ the United States of America Energy Information Administration researched that eighty seven percent of global energy consumption comes from fossil fuels. The worlds most reliable industries provide fuel and electricity to modern societies and have made millions. People have high consumption lifestyle revolving around

In soccer‚ the length of the ball in air when it is kicked is the hang time. Air resistance or adding a curve to the ball will increase its hang time. Hang time can be calculated by H= 1/2 g(gravitational acceleration)times t(time) times 1/2. As the player kicks the ball with the inside of his foot he creates a curve on the ball and increases hang time due to air resistance acting on it. Kicking the ball straight will have a low hang time and just keep it low to the ground. The higher the ball is

PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has
