Question

11 multiple choice 0.5 points to calculate net force, we assign positive or negative values based on ______ of the force. - direction - newtons - size - magnitude 12 multiple choice 0.5 points if i roll a large boulder forward, and uphill, what type of force am i putting on it? and what value would i give this force? - applied force, negative - normal force, negative - normal force, positive - applied force, positive

Explanation:

Question 11

To calculate net force, we use positive/negative based on the direction of the force (e.g., right/up as positive, left/down as negative). Newtons are units of force, size is vague, and magnitude is the amount (not sign - determining). So the correct factor is direction.

When rolling a boulder forward and uphill, the force applied by you is an applied force. The sign (positive/negative) depends on the chosen coordinate system, but typically, if we take the direction of the applied force (forward - uphill) as positive, the applied force here is positive. Normal force acts perpendicular to the surface, so it's not the force here. So the correct option is Applied Force, Positive.

Answer:

A. direction
