How to add to current speed?

I am trying to make an object go faster each time it touches another object (with a permanent force.) But I cannot find a way to add speed to an object that is already In motion.

you can use condition or no condition to set up this depending like you could set a Variable called “Was touched” = true then in the action if the “Was Touched” is true, then add this much force, that would be one way that i would do this.

Action - Force 10 “permanent”
Condition - touch (insert random object) Action - Apply force +1

This is one example, other is the gamedevMat sayed you!
