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

Barack Obama: Man on a Wire By Steven Malik Shelton With the success of president Barack Obama’s reelection campaign which paved the way for him to exhaust a second term‚ he faces dilemmas as dangerous and precarious as he did during his first term. It is quite a balancing act that president Obama must perform if he is to maintain equilibrium between the demands of the wealthy elite and the

calculated. When the resistors are in series‚ the effective length is increased‚ but when they are in parallel the effective area is increased." " ρ is the resistivity of the material: just a constant. See if you can derive the parallel and series addition laws from the relationship at left assuming all the resistors have the same resistivity. 2b What can you do if you need a 35 Ω resistor?" " A. Put one 50 Ω and one 20 Ω resistor in parallel and two 20 Ω resistors in parallel. Then put

Therefore the sum of all the energies in the system is a constant. TMEinitial=TMEfinal 3. Explain the basic ideas that govern the design and operation of a roller coaster. A roller coaster is operated and designed through the application of Physics. The law of Conservation of Energy governs the changes in a coaster ’s speed and height. Simply put‚ the higher an object is off the ground‚ the more potential energy it has - that is‚ potential to gain speed as it falls. As it falls toward the ground

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
