How do we solve problems involving resultant and component forces?
In this post, we are solving problems or make quantitative predictions involving resultant and component forces, as a part of the Prelim Physics course under the module Dynamics and sub-part Forces. To solve problems involving resultant and component forces, we apply the following relationships:
- \vec{F}_{AB} = -\vec{F}_{BA}
- F_{x} = Fcos(\theta), F_{y} = Fsin(\theta)
The following two videos cover a step-by-step approach in solving problems that involve resultant and component forces. The first video covers a large variety of questions that require you to draw free body diagrams to solve, while the second goes more in-depth on inclined plane forces components.
