" joules. The question is, why does an engineer involved in design need this?"
Most power equipment is rated in terms of power and energy. To utilize such equipments, the users are very interested in the energy. After all, that's what they purchase from the utility company to run the equipment, $/kWh. It's world wide standard.

Directly related, first you need to correctly calculate physical phenomena and understand these phenomena correctly. An engineer is a concept, a calculation, a drawing and an implementation. By the way, what is the difference between the operation of a galvanic battery accumulator and a capacitor under load? In physics, there are also concepts such as momentum and angular momentum. How are these concepts interpreted in electrodynamics and mechanics?
They sell quantity, but consume quantity over time. This is interesting for both the seller and the buyer. But creation is power, speed, distance, momentum and torque.
I understand that quantity, power, speed or voltage can be expressed in joules. The question is, why does an engineer involved in design need this? The flywheel also has a corresponding measurement system. But why? Is work as a physical parameter also a unit of measurement in joules? For pricing? I showed everything with links in a post that was blocked. So somehow it's not even interesting.

A scalar quantity (from the Latin scalaris, meaning "stepped") in physics is a quantity whose value can be expressed by a single (usually real) number. That is, a scalar quantity is defined only by its value, unlike a vector, which has a direction in addition to its value. Scalar quantities include length, area, time, temperature, electric charge, work, energy, statistical weight, and so on.
A scalar quantity is also called a scalars. The term "scalar" was introduced by William Hamilton in 1843.
A scalar quantity is a mathematical concept that represents the magnitude of a physical quantity regardless of its direction. In other words, a scalar quantity simply indicates the numerical value of the quantity, regardless of its orientation in space.
The characteristics of a scalar quantity include its representation as a real number, its corresponding unit of measurement, and the ability to be added to or subtracted from other scalars.
Examples of scalar quantities include temperature, mass, velocity, and density. When calculating the sum or difference of two scalar quantities, it's not necessary to consider the direction of each; their numerical values ??are sufficient.
To better understand mathematics, it's important to understand the concept of vector quantities. Vector quantities have not only a numerical value but also a direction. Examples of vector quantities include force, velocity, and displacement.
For example, mechanical power is the product of two vector quantities: force and velocity. Moreover, mechanical power is expressed in two units: watts and newton meters.

What does this have to do with your claims of free energy from a flywheel?

5 farads (F) is a measure of electrical capacity, while ampere-hours (Ah) is a measure of electrical charge (battery capacity). There is no direct conversion without taking voltage into account. At a voltage of 12V,
a capacitor with a capacity of 5F stores a charge of only 0.0167Ah (16.7mAh).
Calculation:
Charge in coulombs (Q): Q=CU =5F*12V=60C (coulombs). Conversion to ampere-hours: 1Ah=3600C
Result: 60/3600=0.016666Ah
This is for those who have the illusion that a battery is superfluous in systems as ballast. No, capacitors are also possible, but the price is against the battery.?
Dear Bi, where in this calculation are joules used as a measure of energy?
Mr. Rakarskiy,
Must I walk you through it?
From my reply yesterday at 4:29pm:
"as those familiar with the science all agree, the charge Q and voltage U define a specific energy W for a given capacitance C. The formulas are well known, W joules = .5*C farads *U volts ^2."
I have inserted the units into the energy formula, in red. I hope that answers "Dear Bi, where in this calculation are joules used as a measure of energy?

Dear bistander?, perhaps you're either clueless or fulfilling someone else's orders so that the system can continue to control energy.
A capacitor is indeed a storage device, but not of energy, but of charge. The charge of a capacitor, or the amount of electric charge accumulated on its plates, is determined by the formula: Q = C?U, where Q is the charge, C is the capacitor's capacitance, and U is the voltage across the plates. Voltage is a parameter of electric potential difference. Incidentally, I believe it's a parameter between 0 and the electric potential of the corresponding spin of the electric field line. (Electrodynamics without electrons).
No pulsed system in an electric circuit without this element is planned. But I have a similar approach with the flywheel. This allowed me to calculate the flywheel as a capacitor.
The book AUTONOMOUS INERTIAL ELECTRICITY GENERATION SYSTEM, which I offer, explains everything precisely. In any case, the reality is visible, but any illusions about the simplicity of the design will be debunked. I'm offering two pages from my book. A guy contacted me who had built a single-flywheel system, but it didn't work for him, as demonstrated by "clown YouTube channels." To explain the result, I calculated the system and showed him the desired rotation speed for a full charge of his flywheel. Incidentally, the guy turned out to be quite accurate and immediately checked and confirmed my calculations (specifically, my system for evaluating flywheel charge). Unfortunately, creating a self-sufficient device still requires a lot of work, and it's not as simple as it seems.
Flywheels are a very dangerous component to operate, especially in those modes where they could be turned into a self-propelled generator.?
Mr. Rakarskiy,
You say: "A capacitor is indeed a storage device, but not of energy, but of charge.

Voltage is a parameter of electric potential difference."
Also, as those familiar with the science all agree, the charge Q and voltage U define a specific energy W for a given capacitance C. The formulas are well known, W = .5*C*U^2.
For use to be derived from the capacitor, the amount of charge contained in the device must vary. Typically this is accomplished by changing the voltage across the plates. That requires work, or energy. So the stored charge represents energy; stored energy.

No capacitor or battery has ever stored any energy, just as no mechanical energy as ever been transformed into electrical energy, they are dipoles to the envioronment, not tanks.
Regards.
The two concepts or theories are not mutually exclusive. They're essentially saying the same thing: by converting potential energy to kinetic energy, work is done.

[QUOTE=bistander;n517149]
a capacitor is an energy storage device, not capable of providing free energy. It can only deliver energy it received when charged. No more.
