Introduction

There are a variety of situations when two or more vectors act together in the same situation. This lesson will inform you how to take those vectors, combine them, and determine the resulting vector, called the resultant vector. Here are the subsections within this lesson:

If you do not have knowledge of vectors (magnitude, direction, their components, ...), first review this lesson.

Engineers, scientists, and mathematicians use vector calculations to build safer automobiles, predict the weather, understand particle forces in nuclear reactions, and more. Here are two examples that require the use of vectors.

For instance, car manufacturers need to know how their products will respond in strange situations, like turning on curves under strange road conditions that involve car velocities and unequal friction occurring on the tires.

Computer programmers, along with properties of physics and meteorology (temperature, pressure, wind speed, ...), create mathematical software models. These models are used to predict the weather. Several models are often accessed especially when strange weather phenomena are possible, like tornados, hurricanes, and blizzards.
