balancing act

[AntonioLao]

A typical problem in Physics 101 goes as follow: An object feels two pulling (pushing) forces of 105 newtons and 5 newtons to the left and to the right respectively. If its mass is 100 kilograms, what is its acceleration?

Solution: Applying Newton’s 2nd law of motion, the answer is 1 m/s to the left (pulling) or to the right (pushing). However, if these forces were incremented, say, to 10,000,100 N and 10,000,000 N, while it’s mass stays the same, it comes at no surprise that the acceleration is the same. Nonetheless, if the mass is zero then no matter how infinitely large are the forces, no acceleration can be imparted to the object. It is a fact that a photon has zero mass while its linear momentum is its energy divided by lightspeed. Therefore, a photon could never be accelerated; hence its linear momentum is constant for a particular frequency-wavelength balancing act combination.

A photon is already accelerated to light speed,how then was that achieved?

It was achieved a priori. It is a logical consequence that only a massless object can move another massless object, this was the case before the big bang.

The speed of photon is not a result of acceleration but its constant kinetic energy given by the product of its momentum and the constant c.

If that is so then you are implying that this is perpetual motion are you not?
That the photon is forever at light speed?

Momentum is the product of an object’s mass and velocity. Do the math. A photon is a measured quantum increment of a wave function and thus only represents “relative mass”. (mass to energy, energy to mass; that E=mc2 thing) These are dimensions, (quantitative measurements) not real unit particles of localized substance.

Thank you Dave for that informative account,the mass must not be messed with?

I only butt in here because we have found the first step to the TOE. If we can use different units besides, Joules, grams, meters, to define our world, if in fact we can find the God particles, we can messily use this as a measuring 'rod"...{brilliant math speak omitted here}

Are you referring to the “Omega particle”? I think you may have watched too much SciFi.
