How do I get the current physical acceleration of object using blueprint?

I need to get the current acceleration of an object in my scene (real physical acceleration, not the input acceleration) and I can’t find the corresponding API. I want to compute the differential of the velocity, but I don’t know how to get the velocity vector of the previous frame. How can I do that?

there’s a node called “Get Current Acceleration” and you can “get velocity / lenght” too, I’m not sure what you need exactly.

I mean, the second options are two nodes, first “Get velocity” (the vector) and then “Get vector lenght” to convert it to and absolute value.
