Raising and Lowering
... A box is lowered with uniformly decreasing speed and less negative velocity. Draw a motion diagram for the box. Is the net force on the box, up, down or zero? Draw a force diagram for the box. Acceleration is positive, e.g. velocity might change from -10 to -5, an increase of +5. The net force = ma ...
