# [S3] Term 2 Week 5 (20-26 Apr) Updates/Debrief

[S3 Physics PMCians]

What we did in 2 hours (PMC LIVE):

We have gone through many questions from the Kinematics MYE DIY Book and the tutors were happy to see that many of us were actively clarifying concepts and asking questions. Keep up this good spirit of learning!

We ended off our LIVE tutorial by (I) breaking into different rooms to compete and complete the usual 4Q team challenge, and (II) the Kahoot quiz.

Before the respective LIVE tutorial sessions begin this coming weekend (30th April, 2nd May or 3rd May), we would like to invite all of you to complete the online webcast lecture on MYE Revision L2.

Many of you might be wonder why we would choose to do the Dynamics Revision also. Based what we have tabulated from the past year S3 tests, examinations and the National Examinations, we observed that the  the complexity of questioning related to Dynamics is increasing. Oh, but this does not mean the questions are difficult, it is just that we need to be clear on the steps to solving. On top of theses, the understanding of Dynamics is essential for us before we embark on the journey towards Work Energy Power and Pressure.

Hence, before we stack more knowledge on other topics, a recap on the procedures is essential.

Special Mention:

Though we may not have our usual face-to-face sessions where you could stay back to ask your tutor questions, we are always here giving full support to your learning in Physics. So, if you have any question(s) to ask, feel free to send them to 9100 1235(PMC HQ).

Meanwhile, stay safe, stay home and, of course, stay awesome!!!

Always with you for your Physics Learning,

The S3PH team (Mr Wong, Dr Li and Mr Gary)

What we did in 2 hours (PMC LIVE):

We have completed the chapter on Coordinate Geometry and practise more varieties of questions in chat challenge! It doesn’t seem easy at first glance. Once we piece the concepts together, bit by bit, everything in the questions start to make sense! Note that this chapter will usually appear as long questions in exam, so do not let your guard down!

To sum up what we have learnt:

Coordinate Geometry

• Recalling concepts from Emaths and lower sec topics

o   Distance between two points

o   Midpoint

o   Equation of a straight line

• Concepts in Amaths Coordinate Geometry

o   Area of rectilinear figures

o   Gradient of a perpendicular line

o   Finding a perpendicular bisector

o   Ratio of length of line segments

Please click the link here for the solutions to the sections below:

• Solutions toTakeaway Questions (Coordinate Geometry)
• More practice, Questions/Solutions to Daily Dose (Coordinate Geometry)

Special Mention:

One of the applications of Coordinate Geometry is map-reading, where we can interpret locations, distances and direction. This is something you learnt in Geography. There are also some other applications in areas such as medical science, creating animations and computer graphics (2D/3D), etc. https://www.youtube.com/watch?v=ERfM7XROLVs

In the next LIVE tutorial, we will continue to practise on Coordinate Geometry. Please continue to revise on all the 5 concepts covered in the booklet.

Once we have finished the questions covering the 5 concepts, we will then proceed to explore on angle of inclination in Coordinate Geometry. Note that this concept is not covered in the booklet. We will also see the some of the question types with this concept in LIVE.

What we did in 2 hours (PMC LIVE):

We have completed our learning on the preparation of salts and ended the chapter with a Quick Fire Round where many successfully applied the thought process while approaching a variety of scenarios.

We have completed a milestone on acids, bases & salts where we practiced equation and state symbol writing. There are much content to memorise so take some time to recap on various types of reactions as well as solubility table. Practice makes perfect.

Special Mention:

Congratulations on our top scorers for the Quick Fire Round on Salt Preparation.

1st – Kong Jia En, RGS

2nd – Tan Xiao Zhuang, RGS; Cayla Tham, CGS

3rd – Allison Law, NYGH; Joshua Sau, ACSBR
