" width="100%" height="480">How to apply vectors in navigation and displacement calculationsScalar multiplication scales a vector’s magnitude without altering its direction, useful for adjusting speed or distance in navigation. For example, doubling the vector **(2, 1)** results in **(4, 2)**, representing twice the displacement. This concept helps students model scenarios like accelerating a vehicle or recalculating a route’s length. Understanding scalar operations ensures precise control over vector-based calculations.
Vectors in navigation are represented as directed line segments, showing both magnitude and direction. In the Singapore secondary 4 math syllabus, students learn to express vectors in component form, such as **a = (x, y)**, where *x* and *y* denote horizontal and vertical displacements. This representation simplifies calculations for real-world paths, like plotting a ship’s course or an aircraft’s trajectory. Mastery of this concept is essential for solving displacement problems accurately.
Resultant displacement is found by adding vectors head-to-tail or using the parallelogram law. For example, if a hiker moves 3 km east and then 4 km north, the resultant vector is **(3, 4)**, with a magnitude of 5 km (using Pythagoras’ theorem). This method applies to scenarios like determining a drone’s net movement after multiple adjustments. Students practice these calculations to model complex journeys in two dimensions.
