What is the four momentum of a photon and how does it relate to its energy and momentum?
The four momentum of a photon includes its energy and momentum in a single mathematical expression. The energy of a photon is directly related to its frequency, while its momentum is related to its wavelength. The four momentum of a photon helps describe its motion and interactions in the context of special relativity.

How is four-momentum conservation applied in the context of particle interactions?
In particle interactions, four-momentum conservation is applied by ensuring that the total four-momentum before the interaction is equal to the total four-momentum after the interaction. This principle helps to understand and predict the outcomes of particle interactions by accounting for the conservation of energy and momentum.
When velocity of body is doubled?
If the velocity of a body is doubled, its kinetic energy will increase by a factor of four. This relationship is because kinetic energy is proportional to the square of the velocity. Additionally, the momentum of the body will also double.
How about if the velocity is doubled but the mass remains the same?
If the velocity is doubled while the mass remains the same, the kinetic energy of the object will increase by a factor of four. This is because kinetic energy is proportional to the square of the velocity. The momentum of the object will also double as momentum is proportional to velocity.
When a speed is doubled does its momentum double?
No, doubling the speed will quadruple the momentum. Momentum is dependent on both speed and mass; hence, if the speed is doubled, the momentum will increase by a factor of four.
What are the four forms of energy that electricity can transform into?
The four forms of energy that electricity can transform into are heat energy, light energy, mechanical energy, and sound energy.
How does kinetic energy change when the momentum is doubled?

What happens to excess energy when the electron jumps from a higher energy orbit to a lower energy orbit in the hydrogen atom?
The electron emits a photon of light which we can see in a spectrograph as color. Four colors are normally seen in a hydrogen atom subjected to energy.
Why a photon cannot rest?
A photon pass through different media at different speed, but that speed always is the highest speed it can achieve at those circumstances. That is because a photon's existence not depend on its structural energy to keep its structure stable but depend on its momenta energy to keep its existence in a dynamic balanced state --- just like an acrobat riding on a single wheeled bike --- he has to swing back and forth to stay on the seat. If you are structurally complex enough, for instances, got four leg like a chair, you can stand on them still; but if you only got one leg, standing still is not the way to keep you upright --- you have to swing back and forth to achieve that. Or you can speed forward all the way or spin. In the case of a photon, it does all three of these movements --- speed forward all the way and vibrate up and down and spins. That is what happening in the photon ---it doesn't have the structural complexity to keep its existence but have to depend on a combination of its momenta energy to achieve that. The forward momentum give it the inertial energy to keep its basic structure and the vibration momentum keeps this structure dynamically stable, the spin momentum keeps the electric field and magnetic field alternatively oscillating to keep a dynamically balanced fields state. There is a dynamically balanced equilibrium point between these momenta forces, before that point is reached, the energy distribution in the photon will only keep going one way --- flow to the lower potential direction. And that direction is the forward speed momentum which not reached the saturated point. Only at that balanced point, the energy distribution becomes two way adjustment mechanism --- if the forward speed not reached the maximum (actually it is the forward momentum not reached the maximum) at that circumstances, vibration energy will be converted into forward momentum; when an outside force give an extra forward momentum, that extra momentum energy will be converted into vibration momentum. That mechanism keeps the forward momentum constant --- note: it keeps the forward momentum constant but not the speed constant, the speed constant is the result of the constant forward momentum. That is the reason when light pass through different media have different speed --- under a constant momentum, it can only achieve different speed at different resistance. In vacuum space there is no resistance so the speed can keep c --- a constant. All these strange behaviour of a photon is decided by its unique character feature --- it is the smallest unit of energy and mass that can stably exist. It doesn't have structural energy to keep its very minimal structure in a thermodynamically stable state but it has to depend on its momenta energy to do so. That is the reason it behaves different from other bigger things --- its thermodynamically stable state is always at a constant speed (result from its constant forward momentum) while other bigger things will achieve a thermodynamically more stable state by losing its momentum energy and slow down.
What is meant by four momentum transfer?
Simply put, four-momentum transfer is the special relativistic spacetime analog of classical (three-) momentum transfer. In classical physics, two bodies can interact and exchange momentum in three spacial dimensions. In particle physics, strictly spatial momentum vectors do not suffice. Instead we use four-momentum, a Lorentz vector. Four-momentum transfer is often referred to as Q^2 is particle physics literature. An interaction that transfer a large amount of four-momentum is a high Q^2 interaction.
When velocity of body is doubled?
If the velocity of a body is doubled, its kinetic energy will increase by a factor of four. This relationship is because kinetic energy is proportional to the square of the velocity. Additionally, the momentum of the body will also double.

If the velocity is doubled while the mass remains the same, the kinetic energy of the object will increase by a factor of four. This is because kinetic energy is proportional to the square of the velocity. The momentum of the object will also double as momentum is proportional to velocity.

What were the four principles of the bohr model?
The four principles of the Bohr model are: electrons orbit the nucleus in fixed energy levels or shells, electrons can jump between different energy levels by either absorbing or emitting photons, angular momentum of electrons is quantized, and the frequency of emitted or absorbed light is directly related to the energy difference between electron levels.
