I'd recommend keeping some mass on the object, otherwise force calculations get a bit weird (acceleration = force / mass which approaches infinity as mass approaches zero). Mass itself won't slow the object down (quite the opposite - inertia due to mass resists slowing down) as long as you've turned off the drag.

It works, I've created a new Physics Material 2D named Bouncy with a friction of 0 and bounciness of 1 and added it to the ball, it now works great. Thanks

Thanks for the reply, this is not the answer, I already have my mass at 0 and gravity at 0, the thing with AddForce() is not clear to me, when to add force? how match? on Start? Every update?
