Wörk and Energy Q4: Apply this definition (WF= Fdcoso) in each of the following four examples. Indicate whether work is positive, negative, or zero. Do the same for AKE. Highlight the correct answers for each: %3D 1. A force in the direction of motion. WF is positive / negative /zero AKE is positive / negative /zero F A force opposite the direction of motion. WF is positive / negative /zero AKE is positive / negative / zero → F A force perpendicular to the direction of motion changes. WF is positive / negative / zero AKE is positive / negative /zero 4. F2 F1 d. Two forces act in opposition to one another. F1 tends to increase KE just as much as F2 tends to decrease KE. The net force is zero, so the object moves at constant velocity. Wzet is positive / negative /zero AKE is positive / negative /zero 2. 3.
