Physics: Complicated to explain read on

Hello everybody, I'm creating a physical game, where you click or touch an object and it always applies the same force. But it seems to stabilize after each time I click on it it gets a different force. I'm doing this:

Event: Touch -> Is Touching object scoop

Action: Apply at 5 Fhysics impulse angle image at 45 pont "colher_cabo" which is the handle of the spoon. In my view it was to always apply the same force. See the example in

AngryWorm

Thanks in advance.
