I was asked the above question in this comment. I understand many students are facing the challenge in sketching distance-time graph given speed-time and vice versa. I have prepared 2 videos to share with you what I taught my students in my weekly coaching programme.

Video 1: Convert Speed-time graph to Distance-time graph.
(10 min)

Video 2: Convert Speed-time graph to Acceleration-time graph.(3min)

(I’m sorry there’s an error in the video at time 2:10s, the acceleration should be -6)

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)
