Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

are parts of physics study. 1) When we walk or run‚ our motion is part of laws of mechanics and thrmodynamics. 2) We eat food which undergoes chemical reactions producing heat energy which is converted into mechanical energy 3) Use of refrigerator‚ pressure cookers‚ washing machines‚ television‚ music system‚ computers‚ etc. are all designed on the principles of physics. 4) When we speak‚ we produce sound properties of which like pitch and intensity are studied in physics 5) Electricity

Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually

http://www.physicsclassroom.com/mmedia/circmot/rcd.cfm What is ‘g force’ in physics? G‚ in physics‚ a symbol relating to gravity. A capital G indicates the gravitational constant‚ as explained in the article GRAVITATION. A lower-case g stands for the acceleration imparted by gravity at the earth’s surface. An acceleration of 1 g is 32. 1 feet per second per second (9.8 m/s2). Fliers and astronauts may experience accelerations many times larger than 1 g. These accelerations are usually expressed

Introduction The purpose of this report is to address the application of treating common vision problems associated with geometric optics. This report will also attend to the nature of the conditions‚ different methods of treating the conditions and compare the success rates for these methods. The two common vision problems that will be concentrated in this report is Myopia (Nearsightedness)‚ Hyperopia (Farsightedness). Nature of the Condition Myopia is a common vision impairment in which close

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic
