How Are Vectors Used in Real Life? Vectors occupy an important place in our lives. You can say that it's the most used mathematical concept in real-world scenarios. Let us discuss a few examples where we use the concepts of vectors thoroughly in the table below. Example #1: The direction of the Plane during Takeoff/Landing- The plane must have the angle of elevation during takeoff and angle of depression during landing. Otherwise, the plan can crash, along with the people in it. Example #2: Acoustics and Music - The Fourier analysis of sounds and other musical notes use vector space analysis. In other words, the acoustic materials in your auditorium absorb or reflect different frequencies, which you can estimate by using vectors. Example #3: Roller Coaster - You must have ridden a roller coaster once, but you must be aware that without vectors, you wouldn't have a roller coaster in the first place. The motion of the roller coaster depends on the gravitational pull of the earth. In other words, when the ride reaches the top of the hill, and speed up when coming down, it's enough to reach the top once again. This series helps students learn to tackle word problems that include vectors. These worksheets are helpful students that are starting to transition to physics type of math.

This is the "meat and potatoes" of the Numbers and Quantities curriculum.
- Homework 1 - Jack is going to a deli from his home. He goes north at 13.5 m/s and east at 6.5 m/s. What is his velocity relative to an observer living in his home?
- Homework 2 - Smith travels to a local garden. Smith travels 130 km from his home towards east. After 2.00 minutes, Smith is 240 km from his home towards north. Find Smith's average velocity.
- Homework 3 - A radar station detects an airplane at a position 180 km from the station's tower towards west. After 3.00 minutes, the airplane is at 210 km away from the radar base towards north. Find the average velocity of the airplane.
A deep understanding of Pythagorean theorem is really helpful here.
- Practice 1 - Henry and Maria are riding bicycles in different directions. They both left from the local Target store. Henry goes south for 30 meters. Maria travels west for 22 meters. How far are they from each other now?
- Practice 2 - Mack leaves the farmhouse to get supplies. He goes 115 km from the farmhouse towards north. After 3.00 minutes, Mack is 195 km from the farmhouse towards east. Find Mack's average velocity.
- Practice 3 - Since the values given are due north and east, connecting the 2 endpoints creates a right-angled triangle.
