Important - When you say "Momentum", do you mean telekinesis? It sounds a lot like telekinesis. Momentum is the thing where you move x speed in a direction, and allow the movement to carry you/momentum to carry you forward.

Why am I asking? Momentum tends to get mentioned a lot by fighters who flip all over the place with acrobatic and close quarter abilities, which can easily create misunderstandings about whether the momentum mentioned was the power being used against them, or their own momentum, and so on.
