3. The four-momentum vector The four-momentum vector is related in a simple way to the velocity four-vector: P µ= mU = (E/c; p~), (16) where [using eq. (1)] p~ = γm~v, (17) E = γmc2. (18) Note that by dividing these two equations, one deduces an expression for the particle velocity: ~v = p~c2 E. (19)

Four-momentum and Calculus of variations · See more » Canonical coordinates. In mathematics and classical mechanics, canonical coordinates are sets of coordinates on phase space which can be used to describe a physical system at any given point in time.

Four-momentum is a relativistic generalization of three-momentum, with the object's energy as the first element. It can be defined as mU, where m is the rest mass and U the four-velocity. Equivalently, one can define four-momentum as (E/c,px,py,pz) where E is the energy and (px,py,pz) the three-momentum.

(18) Note that by dividing these two equations, one deduces an expression for the particle velocity: ~v = p~c2 E. (19) The simplest answer is that four-momentum is like three-momentum, except it has four components - three corresponding to the familiar components of momentum, and one in the "time" direction. This fourth component turns out to be proportional to the energy of the system. That definition of the four-momentum is nice, because it is a nice direct analogy of the usual Newtonian momentum. However, as you note, the four-velocity of a photon is not defined, so that particular definition of the four-momentum is not useful for a photon.

Before going into much detail about kinematics, it is important to The first invariant we introduce is the (relativistic) mass and, using this, the four- vectors of four-momentum, four-force, etc. We emphasize that the photons, and In special relativity, four-momentum is the generalization of the classical three- dimensional momentum to four-dimensional spacetime. 2021년 1월 27일 특수 상대성 이론의 이해에는 간단히는 운동하는 방향으로 길이과 질량, 시간이 변 한다고 이해하면 되겠지만, 조금 깊이있게 이해하려면 아래 4가지 In special relativity, four-momentum is the generalization of the classical three- dimensional momentum to four-dimensional spacetime. Momentum is a vector in Four-momentum.

The four-momentum is useful in relativistic calculations because it is a Lorentz vector.

as proper time, which is simply the time percieved in an intertial frame constant speed Rindler: Ch5: sec. 25-30, 32 Four momentum: This is where things get a bit more interesting. Knowing that the mass of the photon is zero, that implies that the momentum four vector itself is also a null vector (as the mass is the magnitude of the four momentum).
