Calculating Force Components

This video tutorial explains how to calculate the horizontal and vertical components of a force applied at an angle. It uses trigonometry to break down forces into components, providing examples with different angles and magnitudes. The tutorial emphasizes the importance of identifying the angle's position relative to the horizontal or vertical axis to apply the correct formulas.
