Select T-True, F-False, for each statement. If the first is T and the rest F, enter TFFFFF.

A) The work done by a constant force acting on an object is independent of the orientation of the force relative to the motion of the object
B) The work-energy principle is perfectly valid even when there are frictional forces acting.
C) Work cannot be done in the absence of motion.
D) 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)
E) The kinetic energy of an object depends on the direction of the motion involved.
F) The kinetic energy can be positive or negative.
