Graphs in Practical Situations
Could you construct a speedtime graph for the race of this car? Where would you draw steeper lines, when the car is turning a corner or on a straight piece of track? What would a horizontal line in your speedtime graph represent? And what is the car doing when you have a horizontal line in a distancetime graph? Follow the links in which I will explain all you need to know about real life graphs for you to pass your IGCSE GCSE Maths exam. We will first look at conversion graphs. Then we will continue with distance/speedtime graphs. I will explain to you how to interpret each type of graph and how to construct them. I will also show you the commonly made mistakes made by students and teachers(!) when working with these graphs. Then we will continue and I will explain to you how to calculate acceleration and deceleration by looking at speedtime graphs. Finally I will show you what the area underneath a speedtime graph represents and how you can use this to answer questions on your maths exam. So start your maths revision now and study all the example questions by following the links. I will see you there!!
