The discussion revolves around the concept of the normal reaction force in physics, particularly in scenarios where this force may be less than zero. Participants are exploring the implications of a negative normal reaction force and its relation to an object's contact with a track.
The discussion is active, with various interpretations being explored regarding the normal reaction force. Some participants have expressed understanding of the concept, while others continue to seek clarification on the relationship between the normal force and the object's contact with the track.
There is a mention of the normal reaction force being in a downward direction, which raises questions about its implications. The discussion also touches on the idea that the track can only exert a pushing force, not a pulling force, which is central to the participants' reasoning.
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:
