Day 16 - Potential and Kinetic Energy – Part 3




I saw this sentence posted on my Facebook page the other day: "Everything is energy and that's all there is to it. Match the frequency of the reality you want and you cannot help but get that reality. It can be no other way. This is not philosophy. This is physics" - Bashar

This point of view is accepted by many, and they have convinced themselves that physics is aligned with their belief, but this isn't the case. I wanted to write about this today, and show how the law of physics "disapproves" with their approach to life, and even though they believe they are a force of positivity in the world / reality, physics shows that their methods, if anything, are harmful and distractive.

But in order to express my point, I must first explain some more basic concepts in regards to energy, so in this blog I will give an explanation to what is Kinetic Energy and Potential Energy - I've written in my previous blogs that there are many forms of energy, but they have all been divided and categorized as Potential and Kinetic Energies.

As I've mentioned previously, energy has never been seen directly. All formulas for energy thus, express a physical relationship and interaction between physical objects / participles, or as an internal relationship within an object / particle, though you must consider that for any interaction to take place it must happen within some form of separation, as any relationship / interaction happens when at least two objects / particles / entities meet, so basically it's a matter of scale, as the energy is within an object though it is "held" / "created" due to the interactions / movement of the perceived separation of the internal particles. From this perspective it's important to realize that any interpretation of energy is within the paradigm of separation, due to the fact that we, humans, exist in a constant experience, self belief and interpretation of separation in all realms of our reality.

It would have been interesting to see, how physics would have evolved if we were to look at reality from a different starting point, would we have been able to see energy as we know it today, or is how we see it a mere reflection of ourselves as beings that exist in separation from ourselves, each other, nature, the planet, the physical and existence as a whole, trapped in our mind's interpretation of reality and impose this interpretation on nature / the physical, as the only existing truth. On the other hand, assuming our interpretation is accurate, and nature is as separate as we are, does this determine how things must be, does this then mean we must follow natures lead, or can we be the ones living the example and freeing ourselves from our perceived separation, to then having nature and the physical as a whole, follow? Could we not realize ourselves as oneness and equality, and despite how nature is separated, to be the pillar of change, to stand in self honesty and self responsibility, and rebirth ourselves as life? Are we going to hold nature responsible for who / what we have accepted and allowed ourselves to be?

Energy as a concept was initially understood and defined as "life force" as it was seen to be the fuel that allows life to run and operate on, this opens up another point of question as "what is life?" but this is for a later blog.

I ask myself though, whether energy is what is fueling life, thus, making energy a vital and indispensible part of the equation of life, or is it the contrary, where it is life, as the physical, that is fueling energy, where, life, as the physical, is consumed and destroyed as it is violently and mercilessly transformed into energy, and that it is the process of energy creation / transformation that is sucking the life out of existence rather than allowing it to run. Could it be that we have it all in reverse? Is energy the source of life or is energy the result? Can energy exist without the physical? Can life exist without energy? - I will further explore such questioned, but consider that our definitions of life, energy, physicality - all must be evaluated, because as of today they have been defined through a specific lens of separation, and thus have not allowed all rays within the spectrum of reality to shine through the lens, some rays have been hidden through the choice of our lens - can we really trust what we think we know?

So, as I was saying, energy is a concept based on separation, polarity, because for energy to exist one must have some form of interaction which can only be when there are more than 1 that can interact with each other - within this starting point of energy - energy has been divided further into two categories of energies that do not over lap, they exist as a dichotomy - energy, as a complete / whole / full quantity, has been divided to potential energy and kinetic energy, where these two energies are contradicting in nature, they can co-exist but are very strictly defined and separated - as one is the potential / possibility, and the other the actuality / manifestation. Almost like the one is the idea and the other is the application, once you apply the idea it no longer exists as an idea, and as long as it is an idea there can be no physical application.

Potential and kinetic energy are considered to complete each other, the sum of all together is the totality of energy, they represent each other's opposites, they contradict each other - potential energy stands for the ability to do work, the potential, the possibility, whereas kinetic energy referrers to the actuality of doing the work, the movement, the action - and thus, they exist as dichotomy polarities, where, as defined by Aristotle as the philosophical concept of Potentiality and Actuality, like a yen and yang in a way, together both energies complete a whole, yet they are non-overlapping parts of the whole - from a conservation of energy perspective we will see that there is a transformational flow of energy from potential to the kinetic energy, and in some cases back again, depending on the construct of the system -

Conservation of energy and the transformation from potential to kinetic energy and back again, is clearly visible within harmonic oscillation movement, as an ideal system of perpetual motion such as a swing or a pendulum or a spring - this will be explain soon enough, let's begin.


Potential energy is associated with a set of forces that act on a body in a way that depends only on the body's position in space / a force field, it is the energy of an object, or a system, due to the position of the object or the arrangement of the particles of the system within a specific field of force. It refers to an object in a field where the interaction between the object and the field provides the object with the potential to do work, thus potential energy.

As I've said, all types of energy are divided to potential energy and kinetic energy, needless to say there are a few types of energy that function as potential energy, amongst them you will find, gravitational potential energy, electric potential energy, chemical potential energy, elastic potential energy - all have the same structure and principle as the amount of energy is in relation to the object's location within the field / space / substance.

There are various types of potential energy, each associated with a particular type of force. Here is the general expression of the principle for potential energy:

(the change in energy) = (force) X (distance force act through) 

Notice the potential energy is not an independent quantity, it refers to a comparison between two chosen points within the field - the amount of potential energy an object, is not a concrete amount, it means nothing really, because it is relative to it's surrounding, to other objects within the environment, thus, what is concrete is the relationship between two objects, or two points of reference, and thus the relation between two energies - this is the reason the general equation above is defined as the change in energy and the distance the force act through -because that would be a definitive amount and would remain the same in all frames of reference.

Kinetic energy is associated with an object's movement, it's velocity, in relation to the observational reference point. The Kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Kinetic energy is frame dependent, which means that if you watch a train go by it will have an energy dependent on it's velocity according to your view of reference, though for an observer sitting in the train, the train seems to be at rest, and there will thus be no kinetic energy from that frame of reference.

The Kinetic energy of a body or a system is a sum of all kinetic energies of all points / masses of the body, as well as kinetic energy of the center of mass, it is thus most convenient to calculate the kinetic energy from the reference frame of the center of mass, though it is not obligatory - we will find that in the center of mass reference frame the total kinetic energy will be the lowest, because the addition of the center of mass kinetic energy in it's own reference frame will always be zero.

As with potential energy, here too there are other forms of energy, that have somewhat different expressions but are actually kinetic energy, such as rotational energy, where a body spins around it's own axes, like planet earth, there is the movement of the circular / linear motion around the sun, and there is the spin around our own center. Another kinetic energy will be heat, where this is a major point of "energy loss" - how is heat kinetic energy? When energy is transformed into a mass in a collision, or through friction, the particles are energized and as they have more energy they move around faster and thus have more kinetic energy, the temperature of a gas for instance is proportional to the average kinetic energy of its molecules.

At any given moment the total energy will be the sum of the momentary potential and kinetic energies.

This covers the basics of potential and kinetic energy


Now to see the transformation of energy from potential to kinetic and back again - take a pendulum, a swing is a type of pendulum, if we pull the mass aside and release it, it will move back and forth. In it's motion, it loses height in going from either side end to the center - the potential energy that is there due to the height of the mass, disappears when the mass is back down at the center point of the pendulum, at that point the mass's velocity is greatest, the gravitational energy had transformed into kinetic energy, where merely by the virtue of it's motion, will the mass be able to climb back up again. When it reaches the top it pauses for a moment to change direction right before it falls back down again, at that point the velocity is zero, and all the energy is potential energy.

We will find the exact same construct when playing with a spring, we contract it, and at that point it has only potential energy, then when we let it go, it will accelerate until it reaches the center where it's velocity will be greatest and at that point the potential energy will be zero, because at the point of equilibrium the spring is not pulling nor pushing, though again, by mere virtue of the mass's velocity will the spring continue to expand until it will reach it's maximum point - when the velocity will be zero, and the potential energy will me maxed out - both gravitational and elastic potential energy are dependent on the distance the force works on the body - in an ideal system with no energy loss as friction or heat, both the spring and the pendulum will go on forever, from potential to kinetic and back again - we know though, that in reality there will always be some form of energy loss, so eventually the system will dissipate and the energy will run out through heat / friction.

Another point we must not forget, is that even though we are discussing energies, both energies are dependent on and defined in relation to the body's mass - the mass is, in a way, the chamber of energy - as I write the word chamber I am reacting to the choice of words, so to be clear - "chamber" does not by any means define a lesser entity as it might be seen, no, the chamber / holder / body is the substance that without it energy would not be able to do anything, even the work we are referring to is actually done by the physical, energy cannot float around substanceless, in any way you look at energy you will find a mass, as small as it may be, substance is always there, it is that which is containing this energy.

So we see the total energy (E) is a sum of the potential energy (P) and the kinetic energy (K), which are all the forms of energy within the system. Both expression individually can be dependent on time, as we know in each moment the mass on the pendulum / swing / spring is moving back and forth around the point of equilibrium, so the mass, changes it's position in relation to time, and the velocity changes in relation to time, yet their sum is constant, thus not dependent on time, thus, the sum of the two energies, in every moment, is equivalent to the initial energy we had started with, within the law of conservation of energy, and assuming no energy loss that cannot be determined.
