When you calculate the work done by a force on a particle, you multiply the magnitude of the force by the displacement and the cosine of the angle between them. If it's a varying force, in one dimension, you take the integral from the initial position to final position. Does this integral assume that the angle of the force is constant? What if it varies?(adsbygoogle = window.adsbygoogle || []).push({});
