Jesus. Stick to discussions about bullets killing schit that don't involve physics. The discussion of physics here proves one thing: that modern public education is worthless.
First: Einstein. The energy of an object is its mass multiplied by the square of the speed of light. It need have no velocity to have energy. If you think it must be so, explain a fission weapon.
Second: Einstein part 2. Any object (particle) with measurable mass cannot approach the speed of light. In the equations, mass becomes an asymptotic line, meaning that as a particle with mass approaches the speed of light, its mass multiplies exponentially, with the upper limit being infinity. Basically, Einstein's equations showed that no object with mass can approach the speed of light, or it will end up outweighing the universe. Using the speed of light to define the energy of a thing with mass has nothing to do with its velocity. It is a misapplication of physics.
Third: force applied is the definition of work, and is not defined by energy, but by mass and velocity.
You clearly have no idea what you are talking about.
First, the kinetic energy of an object is NOT it’s mass multiplied but the speed of light squared. It is 1/2 the mass multiplied by its velocity squared (E = 1/2*m*v*v). Contrary to your claim, an object MUST have velocity to have kinetic energy, which is the type of energy being discussed.
Second, objects with measurable mass CAN approach the speed of light. I posted the following earlier but you apparently didn’t read it.
Scientific experiments have succeeded in accelerating massful particles to speeds very close to light-speed in a perfect vacuum and much faster than light travels in air, where it is about 90km/s slower, or water, where it is about 25% slower.
For example, the LHC (Large Hadron Collider) has accelerated protons, which have mass, to 299,792,447 meters per second. That is 99.9999991% or just 11 meters per second shy of the speed of light in a perfect vacuum.
Those speeds were actually rather slow compared to those achieved by the LEP (Large Electron-Positron Collider). The LEP has accelerated electrons and positrons, both of which have mass, to 299,792,457.9964 meters per second. That is 99.9999999988% or just 0.0036 meters per second slower than the theoretical speed of light in a perfect vacuum.
Granted, 99.9999999988% is not the same as 100%, but frankly, I don't care. For our purposes here it is close enough and then some.
Moreover, because velocity measurements are relative to a particular point of view, there are galaxies in our universe which are speeding away from our galaxy at greater than the speed of light.
Third, force is NOT the definition of work. Force is not work and does not do work unless an object is accelerated in some direction. The formula for work is Work=Force*Displacement*cosine(theta) where the angle theta is the angle between the direction of the force and the direction of displacement. That said, when work is done, energy is transferred from one object to another or changed from one form to another.
