An inclined plane is a flat supporting surface tilted at an angle‚ with one end higher than the other‚ used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck‚ to a person walking up a pedestrian ramp‚ to an automobile or railroad train climbing a grade. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks‚ ships‚ and planes. Wheelchair

Sam Preusser Mr. Staude U.S. History 25 April 2013 Truman Doctrine VS. Marshall Plan The years after the war brought times of disagreement and argument. The United States worked at this time to contain and control the spread of communism. During the years of WWII and the Cold War this idea was prominent and an issue America thought must be solved. Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making

Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated

Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

never really thought there was any physics involved. I knew you had to use a force to jump up and gravity pulls you back down obviously. An American inventor named George Nissen first invented the trampoline in 1935. (Silvia) A trampoline is defined as an elastic disc of hard canvas held up by metal springs attached to a metal skeletal frame. Kinetic and Potential energy allow you to be able to jump on a trampoline. PE=mgh this equation helps you find political energy due to gravity. (ferg)You calculate

student‚ what have you done to protect our environment? Do you know why we need to conserve our wildlife? We must make a conscious effort to conserve the world’s plants and animals. Plants are essential for our own survival. Plants use the sun’s energy to make food—a process called photosynthesis. Therefore plants are the first important link in the food chain of which humans also form a part. During photosynthesis‚ oxygen is released and oxygen is vital for the existence of life itself.

PHYSICS OF THE PAST One hundred years ago‚ in a poky apartment in Bern‚ Switzerland‚ Albert Einstein‚ then just a 26-year-old patent office clerk still working part-time towards his PhD‚ published five ground breaking scientific papers. Each of these papers‚ written during Einstein’s annus mirabilis ‚ has become a "classic" in the history of science: On a Heuristic Viewpoint Concerning the Production and Transformation of Light ‚ which discusses optical photons and photoelectric effects.

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

1.Introduction: Wildlife conservation is the practice of protecting wild plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wilderness lands to humans. Many nations have government agencies dedicated to wildlife conservation‚ which help to implement policies designed to protect wildlife. Numerous independent non-profit organizations also promote
