Why $W = \vec{F} \cdot \vec{s}$ Fails The formula $W = \vec{F} \cdot \vec{s}$ only applies when the force is strictly constant in both magnitude and direction over the entire displacement. … Read more
1. The Physics Definition of Work In everyday language, “work” implies physical or mental effort. In physics, work has a highly specific, mathematically rigorous definition: Work is done when a force causes a displacement, and there is a component of the force in the direction of the displacement. If a constant force $F$ acts on … Read more
