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

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 began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches
