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:
The normal reaction force is the force that acts perpendicular to the surface of an object when it is in contact with another object or surface.
The normal reaction force is measured in units of Newtons (N) using a force meter or scale.
If the normal reaction force is less than zero, it means that the object is not in contact with another surface or object, and the force acting on it is pulling it away from that surface or object.
If the normal reaction force is less than zero, the object may be at risk of falling or losing stability. This can also potentially cause damage to the object or surrounding structures.
The normal reaction force can be increased by increasing the weight or mass of the object, or by adjusting the angle or surface of contact to increase friction and prevent the object from sliding or falling.
