Note: That's just a theory, but today there are many new theories that contradict this in that they postulate that new Universes are being created and destroyed constantly, on a universe sized time scale. These universes can also collide so "new" matter/energy CAN be introduced in to our universe. Think black holes and white holes. Black holes suck matter/energy from our universe and white holes spit it out into new universes. So in essense the "big bang" was really just a white hole and every black hole in our universe is creating a new universe somewhere else. Or so that one theory goes.
False Statement: Under ordinary circumstances, there is no free interconversion of mass and energy. These events can occur only in the environment of tremendous heat and pressure which exists in a star, or, momentarily, in the detonation of a nuclear device.
That statement is completely false but I kept it to demonstrate how poorly the common man understands this concept. You yourself are converting energy to mass and mass to energy at this very moment. Any warm blooded being with some intellect should be able to figure that out.
A simple concept, is a good old fashioned fire in the fireplace. Wood burning turns to heat and light. Wood has more weight before being burned and there's not as much weight left in the ash, true there is some weight lost to out-gassing but it is negligible. So if, Weight equals mass times (the acceleration of) gravity and the weight of ash is less than wood with gravity being a constant, wouldn't you conclude that energy has mass.
binding energy expressed in mass units is mass defect .mass defect expressed in energy units is binding energy
Photosynthesis is an example of turning energy into mass. E=mc^2 is how energy is turned into mass.
Yes. In a way, energy and mass are closely related; energy HAS mass, mass HAS energy. Energy gets converted into mass routinely in particle accelerators. The kinetic energy from the moving particles gets converted into new particles.
No. Energy has an ASSOCIATED mass. There is no such thing as mass-to-energy conversion, or energy-to-mass conversion. In a nuclear reaction, for example, BOTH mass and energy are CONSERVED. For a more detailed explanation, check the Wikipedia article on "binding energy".
No. Sound is mechanical energy. Mechanical energy does not have mass. And no form of energy has mass. But energy has a mass equivalent per E=mc2 thanks to Albert Einstein.
The Law of conservation of mass-energy indicates that the mass-energy of the universe is constantly changing to maintain the mass-energy constant.
Binding energy expressed in mass units is mass defect. Mass defect expressed in energy units is binding energy.
It isn't exactly converted; every energy has an associated mass, every mass has associated energy.
Um... yes? Light is a form of energy. Energy has mass.
Mass "has" energy, energy "has" mass. The relation is: e = mc2.
Mass and energy are equivalent, so there are exchanges of between mass and energy any time there is a change in motion (kinetic energy). But Atomic energy is the most familiar conversion of mass into energy. The explosion of an nuclear bomb, or the energy generated by a nuclear reactor are consequences of conversion of mass into energy. Energy from combustion is not primarily derived from mass/energy conversion, but from exothermic chemical reactions. In fact, any such exchange between mass and energy would operate in the other direction, as gasses gain mass as they are put into motion (increased kinetic energy=increased mass). But any such gain is so tiny as to be meaningless.
no it does not thermal energy has no affect on mass
Mass and potential energy are not related.
It isn't. This is a popular statement, but it is complete incorrect. Both mass and energy are conserved. Energy: The energy was already available previously, but in another form (nuclear energy, which is a type of potential energy). Mass: The heat or light that is produced is energy; it has an associated mass. For example, the photons (light) that leave the Sun not only take energy, but also mass, away from the Sun. This mass is exactly equal to the "missing" mass.

Any energy - including light - has an associated mass.
Mass Kinetic energy = 1/2 · mass ∙velocity2 Potential energy = mass ∙ (acceleration due to gravity) ∙ height Mass is common to both Kinetic energy is the energy due to motion. The faster an object (mass) is moving; the more Kinetic energy is has. Potential energy is the energy due to position. The higher an object (mass) is off the earth's surface, the more Potential energy it has.fcfytrdddrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrtdjgrfxnzsdfcxzdfgv dorkk
Ofcourse, actually, you have to have mass in order to calculate kinetic energy. Kinetic Energy = 0.5*m*v^2 Where m is the mass. Where v is the velocity. Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.
Energy and matter(mass) are not the same! Energy = mass x c^2 !
binding energy is the energy equivalent to the missing mass in the nucleus
The same as everywhere else. Every mass has associated energy. Every energy has associated mass. Possibly this question is about the energy output of stars. Usually, the more mass a star has the higher its rate of energy output.
Mass and velocity.

No. Mass and kinetic energy are not the same thing.
