How to make physical object respond to collisions but not to gravity.

Getting Started Newbie Questions
#1

Gravity shouldn’t exist in the game I am trying to build.

“physics.setGravity(0,0)” or “object.gravityScale = 0” doesn’t work as expected because of… Newton’s first law of gravity: An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. I don’t want it to move in a uniform motion in straight lines or whatever… I want the object to stop moving on key event’s " (event.phase == “up”) ". Setting velocity = 0 doesn’t work here. Because of Newton…Thanks to him and his first law.  :) 

But I do want the static objects to remain static and my other physical objects to detect collisions… Or is there any other ways to achieve this without using the physics engine…? :)

if you want that behavior you should not use box2d, because of Newton’s first law.
