There are many energy sources that can be readily converted into electricity. In Australia‚ most power plants burn a fuel‚ such as coal‚ or use the energy of falling water to generate electricity on a large scale. Electricity is also relatively

What Is Resistance/Weight Training? Resistance/ weight training is any type of exercise that causes the skeletal muscles to contract and detract with the resistance of an outside force. This outside resistance can be produced in many ways‚ a few examples are: dumbbells‚ rubber exercise tubing‚ your own body weight‚ bricks‚ bottles of water‚ or any other object that causes the muscles to contract. A common name for this exercise is weight lifting. There are many different exercises that fall within

4s and the reaction time while someone is distracting the member is 0.5s‚ and lastly graph matching. 1. Introduction All of us have the ability to move. Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time‚ as we go to work or school‚ participate in sports or even wander around our homes. If we never changed our own motion‚ we would never make it out of bed in the morning. The study

Daniel Osherow ENGR 1301 5 December 2012 Copper Wire Sizes (EE) The diameter of a copper wire is measured by using a system called the American Wire Gauge also known as AWG. This system has predominantly been used in the United States and Canada since 1857. Using this measurement the cross-sectional area of a gauge is able to be found. We then use this area to determine the wires current carrying capacity. The gauge numbers for wire and diameter values work inversely‚ as when one increases the

Because the work is directly proportional to the displacement given a constant force while power is indirectly proportional to work. Therefore we can conclude that power is also directly proportional

Physics (from Greek φυσική (ἐπιστήμη)‚ i.e. "knowledge of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is the natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

What is Physics? Physics is a field of science that shows the interaction between matter and energy. It shows physical processes that help us understand better how our universe behaves. Physics also use scientific method that formulates and tests hypothesis which are based on observations and comprehensions. What are the different fields under Physics?
