QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

20 THINGS YOU CAN DO TO CONSERVE ENERGY Whenever you save energy‚ you not only save money‚ you also reduce the demand for such fossil fuels as coal‚ oil‚ and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide (CO2)‚ the primary contributor to global warming‚ and other pollutants. You do not have to do without to achieve these savings. There is now an energy efficient alternative for almost every kind of appliance or light fixture. That means that consumers

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic

Energy Conservation SCI/275 Energy conservation is so important. Why you ask? Because of the limited amount of nonrenewable energy sources on Earth‚ it is important to conserve our current supply or to use renewable sources so that our natural resources will be available for future generations. Energy conservation is also important because consumption of nonrenewable sources impacts the environment. Specifically‚ our use of fossil fuels contributes to

sparing the energy. Cities must be planned in such a way that the commuting distance is minimized. In industry many things could be done to reduce waste of energy or to economize energy. The maintenance may be tightened; waste heat must be utilized properly. If systems arc streamlined‚ economy in fuel could be obtained. Instead of using materials requiring higher energy‚ those which require lower energy can be used. By effecting minor changes in the existing plants‚ economy in energy could be achieved

Using natural energy resources doesn’t necessarily mean you will conserve any energy‚ yet we do advise every household to research the possibility of implementing natural energy resources to influence their home power supply. This will conserve the fossil fuels we are currently consuming at an alarming rate. Many little things can be done in an attempt to conserve energy in the home. It is knowing how to do these little energy conservation processes that many people do not know about‚ understand

Energy Conservation 1 Energy conservation is the reduction or elimination of unnecessary energy use and waste. This practice may result in increase human comfort‚ personal security‚ national security‚ environmental value‚ and financial capital. There are many activities that people can do to conserve energy and help not only themselves‚ but also the environment and everyone around them. Conserving energy is important because most of our current energy sources are not renewable. When using
