Can you add and subtract constant accelerations?

1I think that the proper title must be : Do accelerations add the same way velocities add in non-relativistic mechanics? so to extend later to what happens in relativistic mechanics. – Frobenius Aug 17 '21 at 10:06

The title and body are asking different questions. – Vincent Thacker Aug 17 '21 at 12:37

This question needs to be edited. title and body are not the same – silverrahul Aug 18 '21 at 12:14

@barrett-barry , this is too short. You have to provide some details. – ACB Aug 19 '21 at 03:22

Of course you can add velocities and accelerations as well. This is a useful concept in relative motion.
Relative velocity $$\vec v_{AB}=\vec v_{AC}+\vec v_{CB}$$
Relative acceleration $$\vec a_{AB}=\vec a_{AC}+\vec a_{CB}$$
But you should always have a clear idea about why you add these velocities or accelerations.[1]
