The Conservation of Energy Essay -- Physics Science Conserving Essays

The preservation of EnergyPhysics Essay The Conservation of Energy Since the beginning of time, vigour has pervaded our earth. These days we rely on it to enhance in our technological developments. We also need energy for a smorgasbord of otherwise things such as to keep our bodies alive and healthy, to run our tools and other technical devices, we also rely on energy to keep nimble in winter and cool in summer. Energy is the ability to do work. People and other things can run out of energy (e.g. a marathon runner) in which case they can no longer hold back the ability to do work. In a mechanical situation, if a machine has energy it has the ability to apply a force to another body. in that location are some(prenominal) different forms of energy and there are many different places by which energy can be garner. Forms of energy let in Potential energy, kinetic energy, gravitational potential energy, elastic potential energy and there are many more. Energy can be gathered in many ways using our natural recourses from the environment, for example solar energy (from the sun) and hydroelectricity (where electricity is gathered by boot piddle) Hydroelectricity is when electricity is generated by rotating coils of wire (rotors) between the poles of a magnet. The rotors are turned by rushing water falling over them. In a hydroelectric plant, water in usually stored in a damn. As the water fall down and rushes over the vanes connected to the rotors it looses gravitational potential energy and ga...
