How to stop collision detection in physics?

Getting Started Newbie Questions
#1

Is there anyway to stop collision detection so that the motion will be unaffected by other physics objects close to it?

#2

by collision im assuming interaction not actual detection. if you dont want it to react anymore you can simply remove its physics body or you can make it a sensor so it wont react

obj.isSensor = true

Thanks!
