F: Physical Energy - The energy witch acts on an object to keep it in motion. Inertia is a familiar term that has to do with this.
I do not think this is valid. Any energy can act upon an object to alter its motion.Hence we have Newton's first law of motion.
An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
F: Mechanical Energy - Energy that is present within machines that keep it running, such as the motion of a gear caused by water falling on the petals.[/qs]
There is no energy present within machines.We can introduce energy to engines by using a fuel or other source of energy,or in this case by the gravitational potential energy becoming kinetic energy in the falling water.
F: Thermal Energy - Heat, the energy which acts on individual atoms within an object.
Atoms do not posses heat but internal energy.Objects with greater internal energy,and thus,higher temperature will transfer this energy to objects with less internal energy {cooler temperature}
The process of energy transfer is what we call heat.
M (Not sure really): Electrical Energy - If you don't know what electricity is, then you shouldn't be on this forum.
Electrical energy is the transfer of energy through differences in charge potentials between unlike point charges.
M (Not sure really): Chemical Energy - Energy that is stored via chemical means and can be extracted via chemical reactions. Example: A batter stores chemical energy witch is later changed into electrical energy.
Chemical energy is the result of physical interaction between electrons in atoms.
M: Matter - Energy that makes up matter I believe.
Actually mass is a property of matter which is the same as energy as realized in Einsteins equation E=MC^2
Potential Energy - Make believe pretend energy that a non-moving body has simply because it can move. Example: A roller coaster is just about to gravitate towards the earth on a huge drop. It has potential energy witch then converts into physical energy (I will be debunking conversions between force energies in this thread fairly soon.) to make it plummet towards the earth.
Gravitational potential energy is the energy present as a consequence of position within a gravity field.Chemical potential enrgy is the potential energy stored within substances such as those found in a battery or even within biological sources such as ATP {Adenosine Triphosphate}
OK, now let's try to reduce some of these energies into ONE ENERGY BECAUSE THAT IS WHAT THEY ARE!!!!
That is correct,however,energy itself is only an abstract understanding that we gain through the conservation of energy law.
