A-Math: Kinematics Step by Step Solution (Strategy To Answer Distance Question Correctly)

In the previous post on the typical questions on Kinematics, I am going to show up the step by step solution to answer a typical Kinematics exam question taken from my A-Math TREQ Book.

Things to take note:

  1. How to get the acceleration equation?
  2. What does it mean by 'momentarily at rest' ?
  3. How to find greatest velocity?
  4. *How to find distance accurately (using a diagram, I called it DD-Diagram; Displacement Distance Diagram)

Every year and in almost every paper, you will be asked to find Distance. The examiners are testing on your understanding of displacement, displacement, momentarily at rest. You must learn how to find it accurately and within the shortest period of time.

Learn from this example well!

A-Math: Differentiation & Integration Application : Examples of Typical Kinematics Questions

I was looking through 2008 GCE O Level Additional Mathematics Exam Papers (Subject Code: 4038) and as expected, there was a Kinematics question (worth 6 marks) in Paper 1.

Kinematics is a application topic for Differentiation and Integration. To master this topic, you do not necessarily need to bring in your physics knowledge though it could be useful at times.

Instead, how I get my students to be a master in this topic is to be familiarize with a KINEMATICS VOCABULARY LIST.

Here's some of the vocabulary words that are useful and common:

  • Momentarily at rest, instantaneously at rest, changes direction of motion, stationary
  • Initial displacement, initial velocity, initial acceleration
  • Greatest displacement, greatest velocity, greatest acceleration
  • Distance travelled in the 4th second VS Distance travelled in the first 4 seconds
  • Maximum distance from Point O
  • Particle returns to Point O
  • Constant Velocity

I would say for Kinematics, it is one of the few topics in A-Math which uses extensive vocabulary. This is also the reason for you to decipher the meaning behind these words.

So do you know the meaning behind these words? I would love to hear about it in the comments section.

I have also taken a few questions from my A-Math TREQ book(Topical Real Exam Questions) to illustrate some common exam questions on Kinematics, further highlighting the importance of knowing your Kinematics well. (Click on the image for bigger view)

How many of you are flooded with tens and tens of school exam papers for all your subjects?

How many of you struggled to answer those questions correctly?

We are about 10 weeks away from 2009 GCE O Level Additional Mathematics Examinations.How prepared are you? Confident to score the results you want or are you desperately helpless and confused?

If you belong to the latter group, please clam down. You still have time but you must be really focused and determined now.

The best way for you to revise (re-learn for some) within the remaining short period of time is to do it One Topic at a Time.

This way of preparing for the O Level exams

  • builds up your confidence gradually,
  • makes it easier for you to digest small bit by small bit and
  • more importantly this method keeps you in a clear and focused mind on what you need to achieve daily.

I have applied this way of revision method for students who seek help in the fire-fighting period like now. (Every year, we would have a few students in our Final Leap Programme, commited to do whatever it takes to create the leap in their O Level results; Darren from Kuo Chuan Presbyterian is a living example, F9 (Prelims) to B3 in O Level A-Maths in 3 weeks!)

NOTE: Final Leap Programme is NOT meant for everyone. Details of this programme will be released in early August.

For the last few months, I have been busy with completing my book on 'O Level Additional Mathematics Topical Real Exam Questions (TREQ) Book'

Finally, it's all ready!

And to thank you for being my loyal reader of, I would like to give you a FREE Introductory Copy of TREQ on the #1 Killer A-Math Topics : Trigonometry.

In this introductory Copy, you will discover:

  • How examiners test your understanding of Trigonometry in the different ways.
  • The various variety of questions being tested for Trigonometry.
  • Your level of competency in the topic of Trigonometry.
  • The MUST KNOW questions to score 'A' in your O levels.
