A friendly Tip : (1)After Watching these videos to build your basic knowledge of the chapter, use question papers to sharpen your skills of solving. (2) As soon as you become comfortable with solving and understanding these chapters, solve them using a stop Watch⏲️. This will help you finish your question Paper on time and some few minutes to spare so that you can check and correct mistakes like miscalculations. (3) Confidence Is power, positive attitude will make you versatile 😎😎😎

Hi Michael, Magnitude simply refers to the size of something. When a question asks for the magnitude of a force, for instance, all that is required is the size of the force without its direction. I hope that helps..
