Why is the forward friction when the object is placed on the conveyor?

- Apr 26, 2019-

Accurately speaking, why should the front friction be applied when the speed of the object is just placed on the conveyor belt?


Because the conveyor is moving forward, and the object remains stationary due to inertia, the relative transmission has a tendency to move backwards, so it will be subjected to forward friction.


Similarly, as long as the initial velocity of the object is less than the speed of the conveyor belt, it will be subjected to the forward friction.


When the initial velocity of the object is equal to the speed of the conveyor belt is not subject to friction


When the initial velocity of the object is greater than the speed of the conveyor belt, it will be subjected to the backward friction.
