# [J1] Lesson 35 (Circular Motion Year End Revision + Sequence & Series+Graphing Techniques + Atomic Structure+Gases Revision )

[J1 Physics PMCians] Let’s Revise – Circular Motion

What we did in 2 hours:

This week, we completed the review of Circular Motion, where we categorised them into
1) Uniform Circular Motion (i.e. moving at constant speed, typically horizontal circle)
2) Non-uniform Circular Motion (changing speed, typically in a vertical circle)
We emphasised the importance of having a problem-solving system, and in all the questions, we followed a simple 3-step process to analyse and solve all circular motion questions.

What you take home:

Circular Motion – Compiled Prelim questions

Special Mention:

Next lesson, we begin our revision on Gravitation!

Till we meet again, have a safe and memorable week ahead!

From you friendly tutors,

Mr Sim & Mr Kwok 🙂

What we did in 2 hours:

Rounding up our Sequences & Series revision is Summation and Method of Differences. We recapped the basic formulae and usage of the Sigma notation (mastery of the fundamentals is essential!) and applied these skillsets to questions involving the Method of Differences.

While the basic MoD idea is every student’s favourite (easiest) part, let’s not neglect the critical followups; apply the three extension applications as practiced and noted in your Secrets Enclosed.

Also, we kicked off our Graphing Techniques revision with some conics practice. Always remember that formatting is key. All other critical features will come easily then!

Special Mention:

More Graphing Techniques this week, involving Rational Functions and Transformations.

See You and Stay Healthy!

[J1 Chemistry PMCians]

What we did in 2 hours:

In this lesson, we have investigated the trends of first ionisation energy in the Periodic Table (across Period & down the Group), and used the idea of effective nuclear charge to describe the trends of ionic and atomic radii and electronegativity of elements.

We then moved onto discuss the chapter of ideal gases, looking at the use of the ideal gas equation, Dalton’s Law of Partial Pressure and concluding with the features of real gases.

Special Mention:

Next lesson, we will begin our revision on one of the notorious chapters – Chemical Bonding. Do come prepared!

Gentle reminder on the additional lesson on 10 Sept, where we will cover Organic Chemistry. Normal weekday lessons will also be cancelled during the week of September holidays.

Work hard and play hard!
