what is the diff. between rest mass and moving mass?

Question

can u explain whats the diff. between rest mass and moving mass?
do gamma rays have kinetic energy?

Answer 1

The rest mass is the inertial mass of an object, measured by an observer relative to whom the object is at rest. With this definition, the rest mass is a kind of measure for how much matter is contained in a body. The rest mass or invariant mass is an observer-independent quantity.


Moving mass is a free mass driven by an external force along an ideal frictionless surface in one dimension.It depends on one's frame of reference.

Answer 2

High energy particles have different masses, rest mass being the mass when it is at rest and the moving mass obtained by applying the Lorentz- Fitzgerald relation. At speeds close to light, the mass increases considerably and at the speed of light, it becomes infinite.

Gamma rays do have energy given by E = h.nu where h is the planck's constant and nu the frequency. Kinetic energy is associated with mass and velocity and in that sense, no. But a high energy gamma ray can spontaneously give rise to a pair production where an electron and positron are liberated and the excess energy of the gamma ray is transferred to the two particles as kinetic energy.

Answer 3

the mass related with moving body is moving mass and the mass related with rest body is called rest mass.
gamma ray have no kinetic energy.

Answer 4

Unless your object is moving at a significant fraction of c (3x10^10 m/s), there is little difference between the two.

Gamma rays have no kinetic energy by the regular definition, KE=(mv^2)/2, but they do have energy determined by their frequency, E=hf

Answer 5

no they dont have kinetic energy brother

as for ur first question i do not understand it properly moving mass is different as it has momentum whivh rest mass does not has at it has no velocity

hope i have given u the correct answer

ALLAH HAFIZ

Answer 6

Energy levels.
