This is because‚ since all of the potential energy was converted into kinetic energy and the kinetic energy has yet to be fully converted into thermal energy‚ the velocity of the mousetrap car is at its highest. Since thermal energy is not at its maximum at this point‚ the car wants to move at a constant velocity. Explain all the aspects in which friction helped your car perform to its

Potential- Energy that is stored in an object due to its configuration Kinetic- energy an object possess due to its motion and mass. Low quality- Energy that is unorganized and do little work. How does entropy relate to the continual energy needs of organisms Entropy represents the disorder of a system which allows the organisms to gain little energy to build and complete their purpose or objective.

According to calculation IT now causes the release of as much carbon dioxide into the atmosphere as nearly 320 million cars‚ worldwide IT now generates CO² emissions of about 600 million metric tons a year. Green IT can help curb this alarming trend. Simply by consistently implementing known energy-conserving approaches‚ the CO² emitted by IT systems can be nearly halved

Identified industries are required to improve their SEC within specified period of three years or face penalty provisions under the mandate of the government. At the same time it provides incentive to efficient industries to trade their additional certified energy savings (that beyond the assigned target) can be with other designated consumers who could use

The annual electricity consumes large amounts of earth energy，while lighting consumes accounts for nearly 25% electric energy‚ low carbon environmental voice is louder and louder.

Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes. Solar cells use a semiconductor material like Silicon (Si) to harvest the energy through; much like a plant uses its Chlorophyll to harness its energy. (2.) Another similarity that can be shared between the two systems would be the way the energy is produced

Abstract (Summary): This experiment was performed to prove that energy exists in many different forms but it can never be created or destroyed. Energy can only be transformed from one type into another. This experiment was executed by mounting a weight onto a weight hook and releasing the pin to allow it to fall. When the weight reached the lowest position it started to rewind in the opposite direction and so the weight started to be lifted. The height was measured and then this was repeated with
