. Review the concept of work. Suppose an object is under the action of a constant force. Make sketches (using arrows) showing the relative directions of the force and object’s displacement when the work done by the force is: positive, negative, zero. 2. Suppose an object travels from point A to point B. Suppose also that two constant opposite forces F1 and F2 act on the object. When might the net work done on the object be positive, negative, zero? Illustrate your answers.
