The Conservation of EnergyPhysics Essay The Conservation of Energy Since the beginning of time, energy has pervaded our earth. These old age we rely on it to advance in our technological developments. We also need energy for a variety of other things such as to keep our bodies subsisting and healthy, to run our machines and other technical devices, we also rely on energy to keep warm in winter and cool in summer. Energy is the great power to do work. People and other things can run out of energy (e.g. a marathon runner) in which case they can no longer flummox 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. There argon many different forms of energy and there are many different places by which energy can be gathered. Forms of energy include Potential energy, energizing energy, gravitational potential energy, elastic potential energy and there are many more. Energy can be gathered in many slipway usin g our natural recourses from the environment, for example solar energy (from the sun) and hydroelectricity (where electricity is gathered by rushing water) 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 falls down and rushes over the vanes connected to the rotors it looses gravitational potential energy and ga...
