A Classical Physics Review for Modern Physics
... potential energy is the negative of the work done by the force (not the work we might have to do “against” the force). Gravity, for example, does positive work speeding up a falling ball; meanwhile the change in the gravitational potential energy is negative. As we see, only a difference in U is det ...

Work Problems
... will cause an increase in speed. This work cannot be negative because a negative work implies that the motion is in the positive direction but the work done in the opposite direction is slowing the object down. For an incorrect statement, the opposite is true: the net work done to the particle must ...
