Get Velocity - Get Speed

[PolyMad]

What is the difference?

And another question: how to get the speed of rotation of an object?

If an objects impacts another objects, it can discharge its energy by moving it, or by imparting rotation to it.
So to check the violence of a collision it is important to have both the functions.

Just found a Collision Event.
But I can't understand how to use it.
Tried the first 3 options of Collision, but it's always going to the Send Event, no matter what.
The last one, On Controller Collider Hit, I don't know how to use it, it does not Send Event or anything.
I hope that Store Force is saving exactly the variable I need: the energy at which the collision happened.
