- Momentum and energy are intricately connected to the concept of force. The terms energy and force are not interchangeable; they are not synonymous. The formula for energy vs. momentum is CONNECTION to E= mc2..
- The energy–momentum relation is consistent with the
- familiar mass–energy relation in both its interpretations: E = mc2 relates total energy E to the (total) relativistic mass m (alternatively denoted mrel or mtot), while E0 = m0c2 relates rest energy E0 to (invariant) rest mass m0.
- Energy is not made of anything. It’s a fundamental concept closely related to time. That’s because energy just represents change in a system. Ultimately, we observe systems to change in time. We’ve developed a concept called energy to account for the amount of change. This is clearly a very convenient and useful concept. For example, the amount of energy in the fuel of your car determines how far you can drive. That is the chemical potential energy in the fuel. Similarly with batteries, the stored energy (also chemical energy) allows a certain amount of things to happen, like powering your phone for a day. There are three underlying concepts in physics: forces, momentum, and energy. Electrodynamics and quantum electrodynamics. Electromagnetism is a classical field theory that is described by Maxwell’s equations. Electrodynamics then includes the Lorentz force law that includes the interaction of the field with charge particles. Such particles also provide the source terms in Maxwell’s equations. In this model, most people would be familiar with the electromagnetic field as a phenomenon that has some value throughout all space. Forces cause change in a system.
An ever-changing array of force fields comes together to build our perceived reality. This field array is ever changing/Momentum is the property that is changed. Energy accounts for how much change. Force fields bind atoms together. These three concepts are axioms from which you build physics, so you can’t actually reduce these concepts any further.
- All things are triune, with binary interactive, just like the holy trinity.
- ONE UNIVERSE DOES NOT AN ETERNITY MAKE.
- ITS NOT THE PEOPLE, ITS THE EVENT.
- BYUND GOOD AND EVIL IS ONLY GOOD.
- One universe is not infinity.

- trictly necessary, it is just useful as an accounting tool; just as accountants themselves are not needed, but can be very useful ;-)Ultimately, with relativity, both energy and momentum become part of the 4-momentum vector, but that’s another story…
- Why is the speed of light so small relative to the size of the universe?The speed of light plays a fundamental role in the structure of our universe and in how we perceive and understand it. It is a universal constant that appears in many important physical theories, such as Einstein’s theory of relativity. According to this theory, the speed of light is the maximum speed at which information or matter can travel in the universe.
When we consider the immense size of the universe, the speed of light may seem small in comparison. However, the vast distances in the universe are precisely why the speed of light is so significant. Light travels at a finite speed, so when we look at distant objects in the universe, we see them as they were in the past because of the time it takes for light to travel across those vast distances.
- When we add electromagnetic interactions to quantum mechanics, we introduce fields. This is done via the so-called minimal coupling Hamiltonian, where the momentum of a particle, p, is now expressed as p → p-eA, where A is the vector potential and is also an operator. So now we have quantum mechanics that includes a field and therefore the wave function now has to include the field. That’s just a straightforward extension of the Hilbert space, which means it’s still a quantum theory.
- In summary, while the speed of light may seem small relative to the size of the universe, it is a fundamental constant that shapes our understanding of the cosmos and plays a crucial role in
