THE LAW OF ATTRACTION
The Power contains the essence of everything I have learned since The Secret was released in 2006. In The Power you will come to understand that all it takes is just one thing to change your relationships, money, health, happiness, career, and your entire life.
You don't need to have read The Secret for The Power to change your life, because everything you need to know is contained in The Power. If you have read The Secret, then this book will add immeasurably to what you already know.
You are meant to have an amazing life!
Now let the magic of your life begin.
I know, all the school books say energy is the ability to do work. But what does that mean? Well it sort of means the ability to make something happen (the nearly-well-known Dave Watson definition). Everytime a force is exerted on something through a distance (which is the definition of work) something had to move, which means something happened. But is that the definition of Energy? My thermo books say work is a process of energy transfer. Not a single one of my numerous thermodynamics text books says energy is "the ability to do work".

| We use energy to run, to make things happen. |
And what about heat flow? Energy can be transferred through heat flow, like when you put a pot of water on the stove and the water gets hotter. Something happened for sure. Something changed. The water got hot and eventually, if left on the hot stove long enough, will start to boil. What forces are involved in this case? There doesn't appear to be anything being pushed through a distance. Does there?
Sugar you eat is "combusted" by your body to produce CO2 and H2O. During this process energy is also released.
This energy is used (among other things) to:
- Operate your muscles
- Maintain your body temperature
Chemical reactions involve changes in energy:
- Some reactions produce energy
- Some reactions require energy
Our society as an "organism" requires energy: 90% of our energy comes from chemical reactions involving the combustion of petroleum products.
The study of energy and its transformations is known as thermodynamics
The relationship between chemical reactions and energy changes is known as thermochemistry.
The Nature of Energy
A Force is any kind of push or pull exerted on an object.
- Gravity is a force which keeps us stuck to the earth.
- The Electrostatic force attracts electrons to protons in an atom.
If you move an object against some force, work is being done.
The amount of work (w) being done is relative to the distance (d) the object is moved and the strength of the force (F) against the object:
w = F * d
Energy, in the form of work, must be used to move an object against a force.
When we do work, our body temperature increases (and we sweat to cool us down). Our bodies are generating Heat energy.
Heat is an energy which is transferred from one object to another depending on the relative temperature:
- Heat energy flows from an object towards other objects of lower temperature
Energy is the capacity to do work or to transfer heat
Objects can possess energy due to their motions and positions, as kinetic energy and potential energy.
Kinetic and Potential Energy
Kinetic energy is the energy of motion. The magnitude of the kinetic energy (Ek) of an object depends upon its mass (m) and velocity (v):
Potential energy is the result of the attractions and repulsion between objects. An electron has potential energy when located near a proton due to the attractive electrostatic force between them.
- Chemical energy is the potential energy stored in the arrangement of electrons and protons.
- Thermal energy reflects the kinetic energy of the molecules of a substance.
Energy Units
The SI unit for energy is the joule ("J"). In honor of James Prescot Joule (1818-1889) a British Scientist who investigated work and heat. (Note: SI is short for the French term Systeme International d'Unites. Which defines metric standards).
Kinetic energy for example is defined as:
Thus, the joule must have units of:
kg*(meters/second)2
and, in fact, 1 joule is defined as:
Traditionally, energy changes accompanying chemical reactions have been expressed in calories, which is a non-SI unit (though still widely used).
1 calorie = 4.184 J
The Nature of Energy II
Energy is a scalar quantity that can perform work in various forms. It has many forms including heat, motion, and light.
- The law of conservation of energy states that “energy can never be created or destroyed” but it can be transformed into other types of energy.
However, Einstein’s equation:
e=mc^2
is a formula where e is energy, m is mass, and c is the speed of light. Mass can be converted to energy, and this equation shows how. The energy produce will be equal to the mass of the object (usually a neutron) times the square of the speed of light.
Mechanical energy has 2 forms, kinetic and potential. These kinds of energy are what cause motion in physical objects.
- Potential energy can be defined as stored energy, and kinetic energy as the energy possessed by an object’s motion. In potential energy there are further divisions, such as gravitational potential energy, elastic potential energy, and electric potential energy.
- Thermal energy, or heat, could also be considered mechanical, although the motion it causes is mostly on the atomic level. The total amount of thermal energy, or heat, in an object is simply a measure of the movement of its atomic components. The hotter an object, the faster the atoms are moving. Thermal energy can cause motion on a larger scale as well, such as when water is heated to steam, which then rises due to its lower density. Steam can be used to turn turbines and do work.
- Waves are a way to transport energy. Mechanical waves need a medium in which to move, and electromagnetic waves do not. Sound waves, ocean waves, and shock waves are examples of mechanical waves. In mechanical waves, energy is moved through a medium, but returning the medium to its original resting position once it has left. A mechanical wave moving through a solid medium, such a rope will cause the whole rope to move at one time or another, but once the wave has passed through, the rope returns to its original position. When one end of the rope is fixed, the energy doesn’t transmit, it only reflects. The loss of energy and seizing of the wave is only caused by the air around the rope that gets moved during the motion of the wave, unless some energy is lost to the motion of the fixed end, such as a loose ring stand.
Sound waves are longitudinal, and the wave vibrates parallel to the direction of the waves motion, whereas the wave in the rope or on the ocean is transverse and vibrates perpendicular to the motion of the wave.
- Electromagnetic waves do not need a medium in which to transfer energy. This is because they are self propagating waves, which means that the electric and magnetic forces produce the other. If the electric energy propelled the wave along a vertical plane, it would produce a magnetic wave that propelled it along a horizontal plane.
- Sound waves are generated by the compression and expansion of air as the energy moves through it. Sound waves spread from a central point in a spherical motion, that is, every direction. The speed of a sound wave is determined only by the medium in which it is moving through. The more elastic the medium, the faster the sound wave can move, and also the longer distance it can travel.
- Light is an electromagnetic wave, as well as a mass less particle known as a photon. Many chemical reactions produce light as a product, like the burning of tungsten in an incandescent light bulb. Although the photon is considered mass less, it is however affected by gravitational forces.
- Visible light makes up a very small part of the entire electromagnetic spectrum, only extending from 400 to 700 nanometers. The longer wavelengths have less energy than the shorter ones, because their speeds are the same so more energy can be moved in a shorter time when the wavelengths are shorter.
- Color is simply different wavelengths of light. Red is the longest and least energetic, and violet is the shortest and most energetic wavelength of light. Pure light is white light, which contains all the wavelengths of light. A Venn diagram of color contains 3 circles, red, green, and blue. Where they meet in the middle they produce white light.
