Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

The three branches that make up the government‚ the legislative branch‚ the judicial branch‚ and the executive branch are features that can be found in one form or another in many different countries. The powers of each branch and the checks and balances that connect them are what gives the American form of democracy its character. One issue arises with the democratic concept of “by the people

In an attempt to not be like Britain and Europe‚ the ‘Founding Fathers’ set out to create a document or documents to allow for the freedom and liberties not available in Europe. After a long set of arguments and time‚ the first document to come out of all that was America’s Articles of Confederation. The founding fathers knew that it needed to be ratified and approved in order to make for a better government at both the federal and state level. The articles of confederation were ratified and signed

The U.S. government has three main branches. These three branches are the Legislative‚ Judicial and Executive. Each of these branches were made possible by the checks and balances in the constitution written by James Madison. Each of these branches all have a very specific job. As well as always needing to confirm with each branch so not one branch has too much power. The Legislative branch consists of the House of Representatives and the Senate. (whitehouse.gov) The constitution allows this branch

The three objects are the bible‚ Steve’s shotgun‚ and Tracy’s badge. The bible was used during all the deaths in The Oath. Steve’s shotgun was used during all the fights with the immortal dragon. Tracy’s badge was used to show dominance against criminals and also in Charlie’s tavern. The bible was an

Karl Marx a sociologist in this time period developed a theory to explain the problems that would soon arise. Marx created one of the three sociologist perspectives‚ conflict perspective better known as the Marxist view. The theory of Marxism begins by focusing on how societies cooperate in order to meet the demand of essential necessities‚ and how industries are managed. Conflict perspective

Negative feedback is a reaction in which the system responds in such a way as to reverse the direction of change. The three components of a homeostatic control system is a receptor‚ this detects changes. The integrator‚ which determines response. Lastly the effector directs some sort of response.The hypothalamus is a section of the brain responsible for the production of

balances were created by our founding fathers to create a fair well established republic and have a separation of power. There are three branches of the government the Legislative branch‚ Executive branch and Judicial branch. These branches were created to check each other and for no one to have total power. Each branch has certain responsibilities that are stated by the first three articles of the Constitution. I believe this type of government works. It has worked for many countries and has yet to fail
