Work Done Negative Examples at Leona Freedman blog

Work Done Negative Examples. On the way down work is negative due to force and displacement pointing in. These work done examples underscore the. In other words, work done against. The work done by the buoyant force of water in the drowning of a. That sign denotes that the work done by the resistive force friction on the object in motion is negative as it reduces the energy (ke). Positive work is done against gravity on the upward parts of a closed path, but an equal amount of negative work is done against gravity on the downward parts. Work is positive on the way up because force and displacement point in the same direction. Hence, if the angle is obtuse, work done is always negative. Unlike friction or other dissipative forces, described in example 7.2, the total work done against gravity, over any closed path, is zero. Positive work imparts energy, propelling motion and change, while negative work resists it, slowing and altering movement. Is force of friciton positive, negative or zero work?
