The discussion centers on the concept of normal reaction force (N) in physics, specifically addressing scenarios where N is less than zero. It is established that when N is negative, the object loses contact with the track and begins to fall due to gravity. The normal force can only act in a supportive capacity; it cannot pull an object towards the track. Thus, if the normal reaction force is zero or negative, the object is effectively "floating" or falling, as gravity is the only force acting on it.

I still don't understand why when the normal reaction force is less than zero , the object will lose contact with the track ?andrevdh said:
If the object is pushing against the track ,the object will surely losing contact with the track right , the object would fall of ?andrevdh said:
Ok, I think I can understand it...andrevdh said:
i am able to understand it ...why N is less than zerogoldfish9776 said:
Is that what you meant to post, that you do understand? If so, that's nice, but why are you telling us?Aayat said:
