Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

find new energy sources. Because present energy sources are running down. So‚ alternative energy is so popular in these days. Because it has no danger to human life like nuclear powerplants‚ it is free to use and it has no waste. There are three types of alternative energy sources: Solar‚ wind and water. This report will be about solar energy. Its purpose is giving some information about solar energy to mechanical engineering students and engineers and calling attention on solar energy. The

Effects of Pollution 1. Environment Degradation : Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus‚ preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species. 2. Human Health : The decrease in quality

In today’s world‚ most of us know that it is important to turn off lights and other electrical appliances to conserve energy‚ but not everyone understands that the reason for the emphasis on cutting back on the use of energy is due to the inevitable depletion of our environment’s nonrenewable resources. Of course‚ electric power is not the only factor that has lead to our supply of nonrenewable resources declining in recent decades. The overdependence on natural gas and oil to fuel our cars and

Forms of Energy Energy exists in many forms‚ and when these change‚ energy is conserved. Different forms of energy include the following: Mechanical Thermal Chemical Electrical Electromagnetic Nuclear energy All of these types of energy have the ability to do work‚ which is also the definition of energy. Additionally‚ they have other properties‚ which are specific to their own specific form. Nuclear Energy Nuclear energy is energy in the

their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total of your system‚ a bullet that is moving
