Energy and mass in relativity theory pdf

If the body in motion measured its mass, it is always the same. However, if an observer that is not in motion with the body measures the body's mass, the observer would see an increase in mass when the object speeds up. This is called relativistic mass. It should be noted that physics has actually stopped using this concept of mass and now deals mostly in terms of energy see the section on the unification of mass and energy.

At this stage, this definition of mass may be a little cloudy, but it is important to know the concept. It should become clearer in the special relativity discussion. The important thing to understand here is that there is a relationship between mass and energy.

Energy is the measure of a system's ability to perform "work". It exists in many forms…potential, kinetic, etc. The law of conservation of energy tells us that energy can neither be created nor destroyed; it can only be converted from one form to another. These separate forms of energy are not conserved, but the total amount of energy is conserved.

If you drop a baseball from your roof, the ball has kinetic energy the moment it starts to move. Just before you dropped the ball, it had only potential energy.

As the ball moves, the potential energy is converted into kinetic energy. The theory is based on the following propositions: 1. The laws of physics are the same in all inertial frames of reference. The magnitudes of all physical entities, as measured by an observer, depend on the relative motion of the observer with respect to the rest frame of the measured entities.

The transformations of all physical entities, from one frame of reference to another, may depend on the methods used for their measurement. All translations of information from one frame of reference to another are carried by light or electromagnetic waves of equal velocity. What is worth stressing here is that Complete Relativity abandons the Lorentz Invariance and the corresponding constancy of the velocity of light.

A comprehensive presentation of Complete Relativity, including its time, distance, mass and energy transformations, is detailed in [9]. The resulting transformations are summarized in Table 1. In this short note, I focus on the Kinetic Energy expression. Substituting in the energy expression Eq. Substitution in Eq. In a cosmological perspective, this is the energy point at which baryonic matter was constructed. More on the application of Complete Relativity to cosmology, including the definitions of dark matter and dark energy, and the prediction of their amounts in the universe, is detailed in [5].

Prediction of the Higgs boson mass For a particle with kinetic energy e, using Eq. Conclusions The present article demonstrates that a relativity theory without the Lorentz Invariance Principle yields a very good prediction of the recently reported mass of the Higgs boson.

It is commonly known that the existence of the Higgs boson has for long been predicted by Higgs and others e. This does not create a conflict between the two theories. On the contrary, the agreement between two theories, each coming from a completely different approach, coupled with the point prediction, reported above, of the Higgs mass should add validity to both approaches. No less important, at high enough energies the theory conforms, at several meeting points, with Quantum Mechanics, the Standard Model of elementary particles physics, and cosmology; while at low enough velocities it conforms with Newtonian mechanics.

The concept of the Lorentz-invariant mass of a group of particles is shown to be applicable to biphoton states formed in the process of spontaneous parametric down conversion.
