his friend’s house. He has to exert a 110 N horizontal force to push the car at a constant speed. How much thermal energy is created in the tires and road during this short trip? thermal energy is created in the tires and road = 110 * 150 =16500 J A 30 kg child slides down a playground slide at a constant speed. The slide has a height of 4.0 m and is 7.0 m long. Using energy considerations‚ find the magnitude of the kinetic friction force acting on the child. The friction force F is parallel

Importance of Electrical Energy Electric Energy We need energy in various forms like heat‚light‚sound etc.The development new technology made it possible to convert electrical energy into any form of energy.This gives electrical energy an important position in the world.The running of the modern industrial structure depends on the low cost and the uninterrupted supply of electricity.In short we can say that a country is developed if the per capita consumption of electrical energy is much higher.

Experiment 4: Work‚ Power and Energy Maria Isabela Mendoza‚ Carmela Miranda‚ Arianne Nagrampa‚ and Vivien Oreo Department of Biological Sciences University of Santo Tomas España‚ Manila‚ Philippines Abstract The experiment performed involved work‚ power and energy. On the first activity‚ the time it took for each member to go up and down the stairs was recorded. Afterwards‚ the work and power done were computed. The most powerful member in the group was student number 2 with power outputs of 239

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

Margaret Mitchell’s novel turned film Gone with the Wind is known as being a timeless classic. The novel was released in June of 1936 and in July of the same year‚ David O. Selznick‚ a Hollywood executive‚ bought the rights to the film for $50‚000. Once Selznick bought the rights to Gone with the Wind he began searching for the perfect cast and refused to any further until he could tie down Clark Gable as Rhett Butler. After a two year delay‚ Selznick was able to finally confirm Gable as Rhett and

In the movie “Gone with the Wind” Rhett Butler is a respectful man. One way we can show he is respectful is his trustworthiness. After Scarlett’s attack Rhett can be seen asking where Ashley and Mr.Kennedy are. He then goes to find them and tries to help. Not only that but when they return he makes up an excuse for where they were. He does this to protect them and keep Dr.Meade and Ashley from being arrested. Other than being trustworthy‚ Rhett is also loving. He proposes to Scarlett and gives her

ENERGY: Energy is the amount of force or power when applied can move one object from one position to another or Energy defines the capacity of a system to do work. Energy exists in everybody whether they are human beings or animals or non-living things for e.g.: Jet‚ Light‚ Machines etc... Energy can have many forms: kinetic‚ potential‚ light‚ sound‚ gravitational‚ elastic‚ electromagnetic or nuclear. The many different natural and renewable energy technologies are by no means breakthrough. Many
