# [J1] Term 1 Week 11 March Holiday (16-22 Mar) Updates/ Debrief

[J1 Physics PMCians] Now we Understand Projectile Motion!

What we did in 2 hours:

In the last lesson, we pulled together our understanding of kinematics equations to solve Projectile Motion, also called 2-dimensional motion.

We realise that we always have to resolve the motion into 2 directions : Horizontal (no acceleration) & Vertical (acceleration = g).

What you take home:

Besides the resources we provided in previous announcements, this week, you took home Kinematics Test C

Previous material provided (for your reference):

1) Kinematic Daily Dose!

2) Collection of Prelim Questions on Kinematics

Special Mention:

Next week, we will begin our journey to explore forces!!

We will begin with establishing a good foundation on drawing proper force diagrams, also called Free Body Diagrams.

Do not miss this upcoming lesson as you’ll need the skills for the entire syllabus!

See you all next lesson!!

[J1 Maths PMCians] Graphing Techniques 3: Transformations

What we did in 2 hours:

We covered how replacing x or y changed a graph in two main ways: Translating and Scaling. Also, given a single expression, how to identify the correct sequence of transformations.

What you take home:

The daily dose has been given out, do try out the questions you’re familiar with!

Special Mention:

This week we will finish up Transformations, as well as get started on a new chapter, Functions.

See You and Stay Healthy!

[J1 Chemistry PMCians]

What we did in 2 hours:

We started to look at interactions between multiple atoms in the chapter of Chemical Bonding. We started off easy with O Level knowledge and started building off from there and worked towards drawing dot-and-cross diagrams for simple discrete molecules.

SPECIAL MENTION:

Next lesson, we shall use our techniques in drawing dot-and-cross diagrams to find out the bond angles and molecule shapes using the VSEPR theory.

Enjoy this song on Chemical Bonding!

See you in class next week!
