Which form of energy is firewood?
In ordinary usage, firewood would commonly be considered a form of potential energy, before it is lit aflame. That is, the wood is then said to possess energy that is ready to be transferred to work. Once on fire, kinetic energy is said to be released. More precisely, the wood may be said to contain chemical energy on the macroscopic level, but both potential and kinetic energy on the atomic and subatomic levels. The firewood energy is renewable form of energy. It can be renewed by growing woody plants.
Do gamma rays have physical mass?
No. Gamma rays are waves, as part of the electromagnetic spectrum, and have no mass at all. A gamma ray is a form of electromagnetic energy. As such, it is said to have a rest mass of zero. A gamma ray, being electromagnetic energy, has some "particle-like" properties, as does other photonic radiation. But it moves at the speed of light in a vacuum and is generally said to be massless.
What can be said about the potential and kinetic energy of the stone as it falls?
we know that according to law of conservation of energy "Energy can neither be created nor destroy, but it can only change from one form to another " just like this before the stone was being thrown , it possessed P.E (potential energy) when when it was thrown it's P.E was converted into K.E (kinetic energy) and when it striked the ground it's K.E was converted again into P.E.
Who said Energy can neither be created nor destroyed but can change from one form to another?
This is called the Law of conservation of mass this comes from an ancient greek that said that "nothing cant come from nothing". Albert Einstein and Antoine Lavoisier have done a lot of experiments proving that nothing can be neither creater nor destroyed but can change from one form to another. There is no offical fact that says who invented this, but there are official information of several scientists that proved that this was right.
What is the significance of the law of conservation of energy?
This is from wikipedia: (Note the bit in italics)The law of conservation of energy is an empirical law of physics. It states that the total amount of energy in an isolated system remains constant over time (is said to be conservedover time). A consequence of this law is that energy can neither be created nor destroyed, it can only be transformed from one state to another. The only thing that can happen to energy in aclosed system is that it can change form, for instance chemical energy can become kinetic energy.
What is a description of energy absorption?
When energy is said to be absorbed, it is merely converted from one form to another as energy cannot be created, nor destroyed. Eg. in a traffic collision kinetic (movement) energy is converted into sound and heat energy.

What is the predominant form of incoming energy from the sun?
Mostly in the form of ultraviolet, visible, and infrared energy. At least that's what Study Island said. ------------------------------------- Electromagnetic energy.
What is the transfer of energy called?
Answer It depends on the type of energy and the type of object. If it is heat energy, then it can be transfered by conduction, convection, radiation, or conversion.AnswerThere are two ways of 'manipulating' energy: work and heat.Work describes the conversion of energy from one form into another. For example, and electric motor does work when it converts electrical energy into kinetic energy.Heat describes the transfer of energy from a warmer body to a cooler body.

Why would the muscle cells need a lot of energy?
To move is to use energy. Energy equals force times distance (crudely said). A muscle cell not only moves itself, but the "arm" attached to it.
Why do Hindus believe in life after death?
As you know, hinduism is related to science or better said, science is coming from hinduism. The hindus see the soul as a form of energy. The first physics law is, that energy cannot be created or destroyed. It can only be transformed to another object. Therefore, if ypu die, the soul will be transformed to another living one.
What does it mean to use energy?
Using up energy is basically converting energy from its original form to such a form in which it becomes useless or it is converted to less usable form. FOR EXAMPLE - When you use electricity to light a bulb. electrical energy is converted to heat energy which is in turn converted to light energy. Now you cannot get back heat energy from that light and hence you cannot get back electrical energy. So here electrical energy is converted to such a form in which is cannot be used further. It is said to be used

If energy can neither be created nor destroyed then can it be said that the origin of the universe is energy?
At a sophomore-level late-night philosophy bull session kind of way, sure, why not.A cosmologist or physicist would pick all kinds of holes in your statement (to begin with, "energy can neither be created nor destroyed" is a bit of an oversimplification, and "the origin of the universe is energy" is something that may sound deep at three AM, but the next morning after the drugs wear off, it doesn't actually seem to mean much of anything).I read something about the law of conservation of energy, one law states that energy cannot be created nor can it be destroyed, it can only change from one form to another. If that's the case, then the universe may have originated from a form of energy and it will end in another form. Then it is a cycle. Maybe they were previous universe and there will be another after this universe.
