They're not the same, but they're related through Einstein's energy-mass equivalence principle, probably the most famous equation in all of science: E = mc2.

Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
Which fuel contains the most energy in the least mass hydrogen or methanol?
The question makes no sense - you can't consider two variables at once - energy and mass. Most energy for the same mass - hydrogen.
How nuclear technologies produce enermouse amount of energy?
Nuclear fission produces energy 2.5 million times that of carbon of same mass. Nuclear fusion produces energy 400 times that of nuclear fission of same mass.
Why does the mass change when the container is not heated to constant mass?
because energy equals mass times speed of velocity squared, if an object has greater energy, that energy can also format into mass, a cold object weighs less than the same object that is hot.
Electromagnetic rays are pure energy?
EM radiation carries energy without a mass-carrying medium. In that sense, they are energy in pure form. However, considering Einstein's mass-energy equivalency (E=mc2), EM energy can, in rare circumstances, be converted to mass at a rate of 300,000,000 Joules/kilogram, and mass converted to energy at the same rate.
How are matter and energy the same?
Energy and matter(mass) are not the same! Energy = mass x c^2 !
Can you convert energy into mass?
No. Mass and kinetic energy are not the same thing.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
How are energy and mass related in a star?
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.
Do photons of a different energy have the same mass?
Yes... and that mass would be Zero. Photons don't have mass.
How does the kinetic energy change if the objects mass is twice as large?
Assuming the larger mass is moving at the same speed as the original mass, the kinetic energy will double.
What percentage of the sun's mass gets converted into energy?
None. There is no such thing as mass-to-energy conversion: both mass and energy are conserved! The total mass before and after a nuclear reaction is the same; so is the total energy. For more information, read the Wikipedia article on "binding energy".
What is the law of Mass states that mass of what you end with in a chemical reaction is the same as the mass of what you start with?
Law of Conservation of Energy
Which fuel contains the most energy in the least mass hydrogen or methanol?
The question makes no sense - you can't consider two variables at once - energy and mass. Most energy for the same mass - hydrogen.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
What does not require matter?
I do not think there is anything that does not require matter. Matter has mass, and mass is the same as energy, so if something does not have mass or energy, it does not exist. Even the smallest elementary particle, the muon neutrino, has energy; therefore it has mass; therefore it is matter.
