How to calculate the Magnitude of a Vector

As you have learned before, vectors have a particular magnitude and a direction. In this section I will show you step by step how to calculate the magnitude of a vector. When you sketch a vector you are sketching a line. What have you learned in the past about calculating the length (magnitude) of a line? The videos below will show you. Make sure to see all three videos for what do you do for instance with negative numbers? After studying all three maths videos and example questions, you will be able to successfully calculate the magnitude of a vector on your IGCSE GCSE maths exam papers.

Solving Example Questions about finding the Magnitude of a Vector

Hopefully you have studied the previous maths video about calculating the magnitude of a vector and are you familiar with the special notation/symbol. Now it is time for you to look at the following two example maths activities in which I will ask questions which will further develop your understanding of this important IGCSE GCSE maths topic. Good luck!

How to solve a Past Paper Question about Vectors combined with Simultaneous Equations

One of you asked on the forum of this website if I could help solving this Past Paper Maths Exam Question about Vectors. Study the Past Paper Question yourself during your maths revision and pass your own IGCSE GCSE Maths exam. You can also let me know on the forum if you don't understand a particular maths topic. I will help you with your maths and answer all your questions. Good luck and have fun!

Example maths questions how to calculate the Magnitude of a Vector

Once you have studied all the maths activities and example questions above, it is time for you to try to answer some questions yourself. Have a look at the FREE maths worksheet I have created for you and try to calculate the magnitude of each vector. You can also download the worksheet for FREE below. On the second page you will find the answer key so you will be able to check all your answers. I encourage you for each question to make a quick sketch of the situation before you start calculating the magnitude. You should also always try to make a sketch on your GCSE IGCSE maths exam for you are bound to make less mistakes and get a higher grade if you do. If you still don't understand how to calculate the magnitude of a vector, then please send me a message and I will help you with your maths by making a few more videos for you. Good luck!
