# [J1] Lesson 36 (Gravitation Year End Revision + Graphing Techniques L2 + Bonding Revision )

[J1 Physics PMCians] Let’s Revise – Gravitation + Circular Motion (Part 1)

What we did in 2 hours:

This week, we reviewed Gravitation, and the types of questions it can be combined :

1) with Circular Motion – e.g Satellite questions, binary stars

2) with Conservation of Energy.

Binary Star – Gravitational Force provides Centripetal force to move in a circle

Special Mention:

Next lesson, we continue our revision on Gravitation with Structured questions!

Till we meet again, may you use this September holiday purposefully and fruitfully!

From you friendly tutors,

Mr Sim & Mr Kwok 🙂

[J1 Maths PMCians]

What we did in 2 hours:

We wrapped our revision on Graphing Techniques, covering rational functions and transformations, as well as some integrated questions.

Graphing Techniques are applied widely in many other chapters, so it is essential to have strong fundamentals here. Revise the standard types of rational functions followups (categorised in Secrets Enclosed!) and also make sure you are proficient at using the replacement method to deal with transformations!

What you take home:

Take-Away questions and other worked solutions are linked here:

Also, take away question solutions and any other worked solutions from the additional lessons on integration and vectors will be uploaded into the same link, please check again on Saturday.

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:

We kickstart our revision on Chemical Bonding this week. We have discussed the strong and weak chemical bonds and the factors affecting them. They include intermediate bonds, where ionic bonds could have covalent character, or some molecules may even exhibit simple molecular structure entirely instead! We then discussed the VSEPR theory, which helps to determine bond angle and shape, that contributed to the polarity of the molecule, ultimately deciding the dominant IMF it exhibits.

What you take home:

The solutions to Q6 of Gaseous State and Periodic Table are below:

Special Mention:

In the additional lesson this Thurs (10 Sept), let us revise Organic Chemistry (Intro, Alkanes, Alkenes), while the weekend lessons will cover the rest of Chemical Bonding, and begin on Equilibrium.

See you and work hard~!
