[J1] Lesson 37 (Gravitation Year End Revision 2 + Functions + Chemical Equilibrium 1)

[J1 Physics PMCians] Let’s Revise – Gravitation + Circular Motion (Part 2)

 

What we did in 2 hours:

This week, we discussed Gravitation in more detail – especially on Satellites in orbit. Specifically, we looked at the

1) period, speed and acceleration of a satellite as its radius changes.

2) how the GPE, KE and Total Energy changes with radius of orbit.

What we did in 2 hours:

We covered Functions, which can be one of the hardest chapters to manage this year! On top of the basic terms, such as rule, domain and range, we looked at Inverse, Piece-wise, Periodic and Composite functions.

 

Always keep in mind that Functions is really a Graphing chapter, and be ready to apply your Graphing Technique skills to identify important range information! Also keep practicing our standard approach to getting the range of a function, this will likely secure some points in your promos!

Special Mention:

Having gone through all our Additional Lessons and having built up your notes on Secrets Enclosed, you should be in a good position for your last lap of revision. This week we will hit the big scoring topic Differentiation, so come ready for some hard work!

 

See You and Stay Healthy!

What we did in 2 hours:

This week has been hectic for us. We did a four hour lesson to revise Organic Chemistry. We begin our revision with hybridisation of carbon and isomerism. We then looked at the main reaction of alkanes Рi.e. halogenation using a free radical mechanism. We completed the lesson by looking at the 7 reactions of alkenes, which can be split into electrophilic addition reactions and redox.

 

During the weekend lesson, we completed our revision for¬†Bonding¬†by exploring the usefulness of IMF in dealing with boiling points and its solubility. We then discussed¬†dynamic equilibrium, with special focus in the application of the¬†Le Chatelier’s Principle.

What you take home:

The solutions to incomplete Organic Chemistry questions are found below. The solutions to other chapters will all be consolidated under the following link.

Do note that the solutions to Test Yourself for Atomic Structure have been edited.

Special Mention:

The arrangement for this week is similar to last week РI will see you on Thurs (17 Sept 4.30pm Р9.30pm) for our revision on Energetics. Over the weekend, we will complete our revision on Equilibrium and move onto the final chapter of Kinetics. The class on Wednesday (16 Sept) at Bishan is still cancelled for this week.

 

Stay safe and healthy!
