[Roland]

entity is the one you collided with

position is the position of the entity when collision happened

normal is the direction of the collision

speed is the speed of  the collission entity 

[Josh]

Speed is the speed of the collision, the magnitude of the point velocity of the collision point on one entity relative to the other.

Bigger speed = hit harder.
