Which factor does NOT affect the downhill force on a slope?

The downhill force on a slope is primarily influenced by the angle of the slope, the weight of the object, and the type of soil. Each of these factors contributes to how gravitational pull interacts with the object on the slope.

The angle of the slope dictates how steeply the object is inclined compared to horizontal, which directly influences the gravitational force pulling the object downward. The weight of the object also plays a significant role since a heavier object exerts a greater gravitational force, thus increasing the downhill force. The type of soil can affect how much friction is generated between the object and the slope surface, which can either enhance or reduce the downhill force.

In contrast, the operator's experience does not inherently change the physical characteristics of the slope or the object involved in the scenario. While an experienced operator may manage the equipment more effectively and make safer decisions based on their skills, the force components themselves are dictated by the physical factors mentioned earlier. Therefore, the operator's experience is not a direct determinant of the downhill force.
