A. equal
2. For us to have a work done on an object, the direction of the force should be to the direction of the motion of the object. B. opposite C. perpendicular D. parallel
3. Why does carrying a 2-kg box across a hall does not exhibit work done? A. The box is so light that it is not showing work done. B. The box's displacement is parallel to the direction of the force. C. The box's displacement is perpendicular to the direction of the force. D. The man carrying the box exerts a lesser force in carrying a very light box.
4. Which of the following situation does NOT show work done? A. a girl running across a field B. a man lifts his baby from the floor C. a man pushes a box across the room D. a man pulling a box across the hallway
5. A man lifts a 10 kg box from the floor and placed it into a 1-meter-high shelf. Is there work done in this situation? A. Yes, because the direction of the force is perpendicular to the displacement of the object B. Yes, because the direction of the force is parallel to the displacement of the object.
C. No, because the object should be placed on a higher position to show work done.
D. No, because the direction of the force is parallel to the displacement of the object​
