What is the Resultant Force and How to Find it (with Examples) In this article, you will learn what the resultant force (also known as net force) is, and how to find it when an object is subject to parallel forces as well as non-parallel forces with the help of examples. How to Find the Magnitude When Force & Angle Is Given?. When a force works in the same direction as a body moves, the entire force acts on the body. In many cases, however, the force points in a different direction. When an object slides down a slope, for instance, gravity acts straight downward, but the object ..., The angle of elevation of the top of the building at a distance of 50 m from its foot on a horizontal plane is found to be 60 degree.
