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)
