Maximal acceleration or maximal accelerations?

TL;DR

This paper reviews the concept of a maximal acceleration for massive particles, discussing how different physical contexts can imply different upper limits for acceleration.

Contribution

It analyzes various arguments for a maximal acceleration and demonstrates that multiple values can be predicted depending on the physical scenario.

Findings

Multiple maximal acceleration values are possible in different situations.

Theoretical arguments support the existence of an upper acceleration limit.

Physical context influences the predicted maximal acceleration.

Abstract

We review the arguments supporting the existence of a maximal acceleration for a massive particle and show that different values of this upper limit can be predicted in different physical situations.
