## What is imaginary energy?

Imaginary energy (also known as ‘Imagination Energy’) is a strange energy produced by Imaginary friends. They are neither a result of science or magic, but some kind of strange force in between we will refer to as Imaginary Energy. All we know is that once someone dreams of a friend, they becomes real.

## What is meant by self energy?

In most theoretical physics such as quantum field theory, the energy that a particle has as a result of changes that it itself causes in its environment defines self-energy. , and represents the contribution to the particle’s energy, or effective mass, due to interactions between the particle and its environment.

**Does energy have to be positive?**

So the physical law that forces energy to be real is: “energy is always real”. Since everything else is squared (quadratic) the energy must be positive.

**Is energy a complex number?**

Electric charge is considered as a form of imaginary energy. With this consideration, the energy of an electrically charged particle is a complex number. The real part is propor- tional to the mass, while the imaginary part is proportional to the electric charge.

### What units make up a joule?

One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

### Is kinetic energy always positive?

Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector.

**What is the self energy of point charge?**

= the total energy of a continuous charge distribution Note # 2: The self energy of assembling a point charge is infinite. Therefore, the total energy of a point charge is infinite.

**What is the formula of self energy?**

(8.28) is numerically equal to U=ϵ02∫E⋅EdV. We can then interpret this formula as saying that when an electric field is present, there is located in space an energy whose density (energy per unit volume) is u=ϵ02E⋅E=ϵ0E22.

#### Is the universe positive or negative?

However, the laws of physics, extrapolations of local measurements, and simple reasoning seem to all tell us that the overall electric charge of the universe is exactly zero. In other words, there is exactly as much positive electric charge in the universe as there is negative electric charge.

#### Why are complex numbers important?

If the formula provides a negative in the square root, complex numbers can be used to simplify the zero. Complex numbers are used in electronics and electromagnetism. A single complex number puts together two real quantities, making the numbers easier to work with.

**Can power be imaginary?**

Reactive power is the imaginary or complex power in a capacitive or inductive load. Reactive power represents an energy exchange between the power source and the reactive loads where no net power is gained or lost. The net average reactive power is zero.
