Can you convert the kenetic energy of something to its mass by solving for m in the equation E=mc^{2}?

Isn't this what happens with virtual particles; a photon becomes a particle/antiparticle pair?Originally posted by pmb
You can't take a single photon and change it into a particle with a non-zero rest mass.
Something I've always wondered about that; doesn't it require that the temperature of the final "lump" must be higher than that of the two original lumps? And that this extra energy accounts for the gained mass, and as the heat radiates off, and the lump returns to its original temp (the temp it had before the collision), the mass of the final lump becomes equal to the sum of the masses of the original two?Suppose there is an inelastic collision - E.g. two balls of putty. Each of which has the same mass and heading toward each other along a straight line (i.e. a headon collision). When they collide they stick together. Then the rest energy of the final lump of clay will be greater than the sum of the two rest masses of the original lumps of clay. The difference in mass being dM = K/c^2 where K = sum of kinetic energies of the two lumps of clay.

Well... the full equation is E^2 = p^2*c^2 + m^2*C^4
Does that help?

Yes, immensely!
what's "p"? (I have an idea its poise?)
The E=mc2 equation, also known as the mass-energy equivalence equation, is a fundamental equation in physics that relates energy (E) to mass (m) and the speed of light (c). It was derived by Albert Einstein and is important because it revolutionized our understanding of the relationship between mass and energy, showing that they are essentially interchangeable.
Kinetic energy is a form of energy that an object possesses due to its motion. In the E=mc2 equation, the "E" represents energy, which includes both kinetic energy and other forms of energy. The mass (m) in the equation refers to the rest mass of an object, which is its mass when it is not moving. Therefore, the E=mc2 equation shows that an object's kinetic energy is directly related to its mass.
The process for converting kinetic energy to mass using the E=mc2 equation involves rearranging the equation to solve for mass (m). This can be done by dividing both sides of the equation by the speed of light squared (c2), which gives the equation m = E/c2. Then, the value for kinetic energy (E) can be plugged in and the resulting mass will be in units of kilograms.
Yes, the E=mc2 equation can be used for all types of energy. This is because energy is a broad concept that includes various forms such as kinetic energy, potential energy, thermal energy, and more. As long as the energy is measured in joules (J), it can be used in the equation to calculate the mass of an object.
Einstein's theory of relativity is based on the concept that the laws of physics are the same for all observers in uniform motion. The E=mc2 equation is a direct consequence of this theory and demonstrates how mass and energy are interrelated. Additionally, the equation is used in the theory of relativity to explain the behavior of particles traveling at the speed of light.
