In E-Math, one of the commonly asked questions in Paper 1 usually involved Kinematics (which is closely associated with motion) and in E-Math, we discuss about Distance, Speed and Acceleration.
One of the important definitions all students must know is acceleration. It's defined simply as the change of velocity with time.
I'm going to use the following example to highlight the types of information we can obtain from a speed-time graph. It contains my handwriting, hope it works well for you ;)
Try out the question before peeping at my solutions. (Highlighted parts = important formula)
