Jad A asked: Can u please explain the different energy transfers that take place for the following energy resources....
Geothermal Energy
Nuclear Energy
Hydroelectric Power
Solar Power
Biomass
Wind Power
Waves
Tidal Power

SnizzleDizzle asked: According to the law of conservation of energy, energy is not created from nothing. It is either converted from mass or from other types of energy. In this case, where does the energy for gravity come from?
For instance, the force pushing down the water in Niagara ...

N.H.F asked: According to the conservation of energy, energy is transformed into other forms of energy. In real cases, for example, in engines, not all chemical energy (from the fuel) is converted to kinetic energy (correct me if I'm wrong) because some of the input energy is dissipated as heat ...

Justcurious asked: When you insert a dielectric between the plates of a capacitor, the energy of the capacitor decreases.
1). Where does the energy go to to create the difference from before?
2). Also, what would happen to the energy if the capacitor remained connected to the battery and the ...

My son is due 8-23-09 asked: For physics class I have to design my own experiment.
I want to conduct an experiment answering how to convert energy from a waterwheel to a light bulb.
How exactly can I get the energy to convert?
Will I have to get a generator or something?
I know ...

sassychickensuckerboy asked: The first law states that "energy cannot be created or destroyed". Does taking energy from other dimensions really imply "creation", or just another way to obtain energy?
Does it boil down to a violation because the extra dimensions have not been proven yet? Therefore, it "could" be a violation ...

Lalen asked: Photosynthesis, the biological conversion from light energy to chemical energy... But I thought photons have zero mass (therefore zero energy?), so where is this energy coming from? Does it just refer to the extremely small energy that comes from a photon's momentum?JONAS

ScarecrowEyes asked: I know that when an object is held at a particular height above the Earth, it has a quantity of potential energy associated with it, but no kinetic energy. When the object is dropped, it loses potential energy and gains kinetic energy, thereby ensuring that energy is ...

admin asked: I know it is possible that sub-atomic particles are made of energy-like things called quarks. According to my understanding of them they are more like energy than they are like matter. Unfortunately I have a very basic understanding of these particles and their relationship with energy. I have ...
