Curved trajectory + easing

I want to make an object follow a curved trajectory through the air, only towards the end of the curve i want it to ease to a stop. How do I do this? I tried fiddling around with forces but it doesn’t give me the effect i want. Searching on google throws up bezier curves and itween, but im not sure if thats applicable to what i want.

The question you should ask yourself is, What behaviour do I expect if something comes in the middle of the trajectory? If nothing, then use iTween, otherwise use physics.

I would suggest you look at iTween examples here, iTween for Unity by Bob Berkebile (pixelplacement)
