Question
- Select T-True, F-False, for each statement. If the first is T and the rest F, enter TFFFFF.
- A) The work done to raise a box onto a platform depends on how much time it takes to raise it. (Neglect friction, assume it starts on the ground at rest, and ends up resting on the platform)
- B) The work done by a constant force acting on an object depends on the orientation of the force relative to the motion of the object
- C) Work cannot be done in the absence of motion.
- D) The kinetic energy of an object depends on the direction of the motion involved.
- E) The kinetic energy can never be negative.
- F) The work-energy principle is perfectly valid even when there are frictional forces acting.
