Net displacement involves calculating the overall change in position from a starting point, considering multiple directions and distances. To find net displacement, break down movements into vertical and horizontal components, sum them, and apply the Pythagorean theorem. For example, moving 130m north, 50m east, and 40m south results in a net displacement of 102.9 units at an angle of approximately 60.9 degrees from the horizontal. Trigonometric functions, such as tangent, can be used to find angles based on the opposite and adjacent sides of the resulting triangle. Visual aids like diagrams are recommended for clarity in understanding vector displacement and angles.
