text: For example, when a ball is held above the ground and then dropped, the work done by the gravitational force on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).
text: Therefore, work on an object that is merely displaced in a conservative force field, without change in velocity or rotation, is equal to minus the change of potential energy P E {\displaystyle PE} of the object,
text: This says that the work ( W {\displaystyle W} ) is equal to the line integral of the force F along a path C; for details see the mechanical work article.
