What does it mean to say energy is conserved within a system?
When an object is accelerated along a distance that requires energy. If the object is then slowed to a stop by a breaking system that gets back that energy then the energy is said to be conserved
What is energy defined?
I suggest you read the Wikipedia article on "energy". There is really no definition of "energy" that's short, easy to understand, and accurate; the reason for this is that "energy" is a fairly complex concept. You might say that it's a magnitude in physics that is conserved - you can't increase or decrease the total amount of energy. However, note that there are several other magnitudes in physics that are also conserved.
Need an explanation why kinetic energy is always conserved during elastic collision what is meant by conserved?
In this context "conserved" means the total kinetic energy of all the objects is the same after the collision as before the collision. Note, the TOTAL is the same but the individual kinetic energies of each object may be different before and after. When two or more objects are about to collide they have a certain total kinetic energy. It is common that during the collision some of the kinetic energy is transformed into heat. So after the collision the total kinetic energy is less then before the collision. This is a non-elastic collision. There are some collisions, however, in which none of the kinetic energy is changed to heat. These are called ELASTIC collisions. So the total kinetic energy doesn't change, or is "conserved". There is another possible non-elastic collision. If during the collision there is an explosion, then its possible for the objects to have a larger total kinetic energy after the collision as they aquire some of the explosive energy. Finally note, that in all collisions the TOTAL vector momentum is the same just before and just after the collision. So in a collision momentum is always conserved.
To say that electric charge is conserved is to say that electric charge?
To say that electric charge is conserved means that the total amount of electric charge in a closed system remains constant over time. This principle is a fundamental aspect of electromagnetism and is supported by experimental observations.
What is the difference between quality and quantity of energy?
From thermodynamics perspective heat is also known as quantity of energy and work is known as quality of energy,the energy which is in organised form and which can be utilized for producing any kind of effort and one more thing we generally say energy is conserved here we means quantity of energy is conserved. However,quality of energy depends on the efficiency that ideally is a function of temperature. So as we increase the source temperature quality of energy increases.(carnot’s formula η =(1-Tsink/Tsource)
When did albert Einstein invent e equals mc2?
In the beginning of the 20th century. He proposed mass-energy equivalence in 1905, and set out to mathematically express this. E = mc2 shows that energy can be converted into mass, and mass into energy. Thus, we no longer say that mass is conserved, or energy is conserved. But rather, we say that mass-energy is conserved.
What does it mean to say momentum is conserved?

How are energy and mass conserved by living systems?
Not quite sure what you mean; let's just say that living systems don't require any extraordinary efforts to conserve energy and mass, because that's what they do naturally, i.e., "be conserved". There is no known way to violate conservation of energy or mass.

Is it grammatically correct to say you will get look into it?
No. You can say that you will look into something, or that you will get someone to look into something, but you cannot say 'get look'. These are all correct: 'I will look into your problem with the leaking washing machine tomorrow.' 'I will get a plumber to look into your problem with the leaking washing machine tomorrow.' 'I will get your problem with the leaking washing machine looked into tomorrow.'
Will it is be grammatically correct to say that there is nothing wrong with this machine?
It is grammatically correct to say: There is nothing wrong with this machine.It is not grammatically correct to say: Will it is be grammatically correct to say ....The correct way to write that or say that would be: Would it be grammatically correct to say....

Which is correct machine gun or automatic machine gun?
Machine gun or machinegun. All of them are automatic, so it is redundant to say that. There is no such thing as a semi automatic machine gun, or a single shot machine gun. That answer is correct, but many people use the term fully automatic machine gun or full auto machine gun to specify they are not talking about a semi-auto pistol or rifle, which are commonly referred to as autos, and sometimes that term confuses people.
Is it correct to say that an incandescent bulb and a light stick use the same form of energy to create light Why or why not?
No. One is chemical energy, the other is electrical energy.
