At Speeds Near Light Mass Does not actually Change unless you apply more energy. A New look at E=mc2

E = mc², equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other. In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c²) is equal to the kinetic energy (E) of that body.

In physical theories prior to that of special relativity, mass and energy were viewed as distinct entities. Furthermore, the energy of a body at rest could be assigned an arbitrary value. In special relativity, however, the energy of a body at rest is determined to be mc². Thus, each body of rest mass m possesses mc² of “rest energy,” which potentially is available for conversion to other forms of energy. The mass-energy relation, moreover, implies that, if energy is released from the body as a result of such a conversion, then the rest mass of the body will decrease. Such a conversion of rest energy to other forms of energy occurs in ordinary chemical reactions, but much larger conversions occur in nuclear reactions. This is particularly true in the case of nuclear fusion reactions that transform hydrogen to helium, in which 0.7 percent of the original rest energy of the hydrogen is converted to other forms of energy. Stars like the Sun shine from the energy released from the rest energy of hydrogen atoms that are fused to form helium.

Kinetic Energy

As an object gets faster the more energy is required to move it. The standard equation for the energy of movement (kinetic energy) is:

That is, kinetic energy is equal to half the mass multiplied by the velocity squared. This is often called Newtonian kinetic energy. Note that the velocity term is squared. This means, for example, that it takes far more than twice the energy to travel at twice any particular speed. We can see this by working through the equation for two values of v, where: v = 50 ms-1 and v = 100 ms-1 respectively, both with the same mass of 10 kg:

This equation is fine at “low” speeds, i.e. the speeds we encounter in everyday life.

However, believe that mass appears to increase as the speed increases and so the Newtonian equation for kinetic energy must start to become inaccurate at speeds comparable to the speed of light. So, how do we compensate for the observed mass increase?

What Does this all Mean

Basically the belief is that all matter has energy that makes up it’s entity. The amount of energy held by the entity is in direct proportion to the units Mass.

If you look at E = mc²  and solve for mass the equation looks like

Since C is constant Energy and Mass are totally dependant on each other, and it is obvious that if you increase energy that the mass will change too.

However this is not the full formula. E = mc²  is the energy potential within a stationery object. Once it starts moving we have to take into account its velocity.  The formula as follows is the full formula. You can see that when an object is not moving then the bottom line will equal 1. Thus holding E = mc²  as true.

Full Formula

Energy is calculated by the Mass x Speed of light squared divided by square root of 1 minus the velocity squared divided by speed of light squared.

If mass increases then yes the energy increases, but also true if velocity increases so does the energy increase. So it is possible to increase an objects velocity without increasing its actual mass.

Now when the objects velocity comes closer to the speed of light the bottom part of the line approaches a result of 0, and then the equation falls apart.

If we rearrange the formula to solve for mass (m)

If you increase Energy then Mass will increase, however the strange thing happens is that as you increase velocity the mass actually decreases, if the energy stays the same.
