PHYS 200 - Lecture 14 - Introduction to the Four-Vector - Yale …
The four-vector is introduced that unifies space-time coordinates x, y, z and t into a single entity whose components get mixed up under Lorentz transformations. The length of this four-vector, …
Definition 12.1 The 4-tuplet, A = (A0; A1; A2; A3), is a “4-vector” if the Ai trans-form under a Lorentz transformation in the same way that (c dt; dx; dy; dz) do. In other words, they must …
5.2: Math Tutorial – Four-Vectors - Physics LibreTexts
Extending this to spacetime, a four-vector is a quantity with magnitude and direction in spacetime. Implicit in this definition is the notion that the vector’s magnitude is a quantity independent of …
