Explanation:
it keeps moving
The net force acting on the object is equal to zero. The object is either at rest or moving at a constant velocity. Figure shows a flower pot hanging at rest.
Constant Force: • In this mode, the deflection of the cantilever can be used as input to a feedback circuit that moves the scanner up and down in . z, responding to the topography by keeping the cantilever …
