A thought occured to me thinking about the quantum slit experiment. Upon firing an electron or particle it would impart an opposing force on the machine shooting it. The direction if this force should give you the direction your electron should be going and allow you to predict if it went through a slit or not. When you do, does it count as a measurement and stop the interference pattern? Or does the particle need to be measured?
Imagine for a moment it does still create an interference pattern because you didnt measure the particle itself. If you then measure the electron if and when it goes through a slit AFTER you measured the force in the opposite direction, would the energy be at odds compared to a particle going the exact same direction but it wasn't measured (because it would go through both slits and none at the same time and thus have multiple potential directions)?
