# [J1] Term 1 Week 9 (2-8 Mar) Updates/ Debrief

[J1 Physics PMCians]

What we did in 2 hours:

This week, we re-looked the understanding of Displacement, Velocity and Acceleration. We emphasized that to know the acceleration, you only need to look at the net Force acting on the body.

After completing the graphing skills needed, we moved on to the 4 kinematics equations.

What you take home:

Take time to practise more kinematics questions with our Daily Dose!

[J1 Maths PMCians] Graphing Techniques 2: Rational Functions

What we did in 2 hours:

This round of graphing involved rational functions, where we dealt with fractions of polynomials with linear denominators. We were able to sketch a graph by finding its asymptotes and intercepts, as well as stationary points where required. And we also picked up GC skills to help us with these operations when allowed.

What you take home:

Do try the Daily Dose questions on Rational Functions if you’re feeling confident!

Special Mention:

This week, we will be carrying on with the rest of Rational Functions. We will also be having a small quiz on Conics and Rational Functions, so do come prepared!

RI Class: This week we will be finishing functions, consolidating all the techniques in the chapter as well as practicing more on composite functions and exploring its different question types.

[J1 Chemistry PMCians] A closer look at the anatomy of atoms

What we did in 2 hours:

This week, we have helped to demystify some of the questions your secondary school teacher has refused to answer when you picked up Atomic Structure then. We also hoped that you have picked up more confidence in writing the new electronic configurations for particles. Make it an effort to try some of our shortcut methods when trying your tutorial questions too.

Also, congratulations to all who did well in Atomic Structure Test A.

What you take home:

You should have received the “Everything you need to know” for Atomic Structure. Use it to help recap main ideas. Solutions will be provided next week.

Special Mention:

Next lesson, we will look at Ionisation Energy, which is a concept which will appear again in later chapters.

Here is a engaging video on the History of Atomic Structure. How you picked up atomic structure in chemistry is a close representation of how scientists developed theories on atoms too.
