In order to define acceleration of a body in it’s own frame, we need to first prove that acceleration is a four vector so that its dot product can then be labelled as acceleration squared in rest frame. For velocity and displacement vectors, we can show that they have a constant dot product. But how do we prove that for acceleration?

In order to define the acceleration of a body in its own frame, we need to first prove that the acceleration is a four-vector so that its dot product with itself can then be labeled as acceleration squared in the rest frame. For velocity and displacement vectors, we can show that they have a constant dot product. But how do we prove that for acceleration?
