In theoretical physics, an invariant is an observable of a physical system which remains unchanged under some transformation. Invariance, as a broader term, also applies to the no change of form of physical laws under a transformation, and is closer in scope to the mathematical definition. Invariants of a … See more
In classical and quantum mechanics, invariance of space under translation results in momentum being an invariant and the conservation of momentum, whereas invariance of the origin of time, i.e. translation in … See more
In the field of physics, the adjective covariant (as in covariance and contravariance of vectors) is often used informally as a synonym for "invariant". For example, the Schrödinger equation does not keep its written form under the coordinate … See more
Wikipedia text under CC-BY-SA license Invariant mass - Wikipedia
In particle physics, the invariant mass m0 is equal to the mass in the rest frame of the particle, and can be calculated by the particle's energy E and its momentum p as measured in any frame, by the energy–momentum relation: or in natural units where c = 1,
This invariant mass is the same in all frames of reference (see also special relativity). This equation says that the invariant mass is the pseudo-Euclidean length of the four-vector (E, p), calculated u…Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 9 mins

5.2: Invariance of Physical Laws - Physics LibreTexts
The laws of physics include only those that satisfy this postulate. We will see that the definitions of energy and momentum must be altered to fit this postulate. Another outcome of this postulate is the famous equation \(E = mc^2\), which …

Why is mass an invariant in Special Relativity?
May 20, 2020 · In Special Relativity, when we say a quantity is an invariant, we mean that it is a Lorentz invariant. What this means is that when you apply the Lorentz transforms to any frame of reference, the magnitude of the Lorentz …
