Mechanical energy
The chemical energy is transformed in kinetic energy.
-- A bowling ball rolls off of a shelf. It spends some fraction of a second converting its gravitational potential energy into kinetic energy, whereupon it dramatically expends all of its mechanical energy upon impact with the floor. -- Water pours over a waterfall. Its gravitational potential energy is converted to kinetic energy on its way down to the valley below the falls. If you stick a waterwheel or turbine into the cascade in the right way, you can rob some of the water's mechanical energy to generate electricity or grind wheat.
The motorcycle's gasoline is potential energy. The energy is released as a chemical reaction (chemical energy) and converted to heat (heat energy). It then becomes converted to kinetic energy with the movement in the engine, and subsequent movement of the motorcycle.
Coal is a chemical compound which contains chemical energy. To convert coal into mechanical energy, you use it (burn it) to produce heat and use the heat to boil water, the steam from which will drive a steam engine which delivers mechanical energy.
potential chemical energy
heat and sound energy, i think
Converts chemical potential energy in the fuel to mechanical work at the shaft.
In a hydro plant the water has potential energy which turns to kinetic when it is allowed to fall into the turbine. Or in a gasoline engine or a jet engine, the potential chemical energy in the fuel is released by burning it and it results in kinetic energy of the vehicle.
Yes, the energy output of an engine is governed by the chemical potential energy of the fuels. Assuming that the extra potential energy could be turned into useful work, there would be an energy advantage of diesel over petrol.
The energy released from gasoline when it is used in a gasoline engine is chemical energy.
Potential, then chemical, then mechanical.
Chemical compounds, like oil or coal, hold potential chemical energy in the powerful molecular bonds with the compound. If such a chemical compound undergoes a chemical reaction (in this case in an internal combustion engine), the potential chemical energy will be released in the form of thermal energy. Of course, no energy transformation is 100% efficient as some of the potential chemical energy is either not converted at all or converted into a different form of energy. Take the example of a fire in one's fire place. Although a large percentage of the potential chemical energy in the wood is converted into thermal energy that we can feel as heat, some of the energy is converted into light, that we can see as the brightness of the fire, and some is converted into sounds, as we can hear in the roaring of the fire.
A combustion engine transfers thermal energy to move one or more pistons that provide power. An example of a combustion engine is an engine in a car.
By using chemicals in a rocket engine to raise a vehicle high above the earth's surface, the vehicle will gain gravitational potential energy. It will also gain kinetic energy, depending on what trajectory it follows
A combustion engine converts chemical energy in gasoline to mechanical energy in the engine.
When fuels are burnt, the chemical potential energy in the fuels is converted into heat and light energy. Initially, such energy will be converted to heat. In a fire, part of that will be radiated away as infrared radiation or light; it is also common that the heat will increase the pressure and make things expand - which is what happens in a gasoline or diesel engine.
