[S4] Lesson 26 (Dynamics Revision + Equation of Circles + Stoichiometry EOY )

[S4 Physics PMCians]

What we did in 2 hours:

On the 27th and 28th June, the S4PH has come together to cover the following during our weekly zoom lessons:

1) Secret Enclosed on Dynamics Concept 1 and 2

2) The Final Lap MCQs Q1 to 21

Always remember:

1) A free-body diagram is the first step to solve any forces related questions before you use the F(res) = ma

2) To explain water resistance or air resistance-related motion, a free-body diagram is helpful. And, remembering how drag force is related to speed is essential.

3) For any forces to qualify as Action- Reaction pairs for N3LM, go through the 4 critierias.

What you take home:

We will continue with Dynamics Revision Lesson 2 where we will continue to think aloud in applying the concepts to the structured questions.

Special Mention:

Should you have any questions, please feel free to send in your questions (and attempted workings) to 9100 1235. We will do our utmost to assist you in the questions.

Take care and Always with you,

The S4PH Tutors

(Mr Shane, Dr Li and Mr Gary)

What we did in 2 hours:

We started on Circle Revision this week.  We learn to recognise the equation of a circle and find the centre and radius of the circle. We practice variety of question, recapping the various properties of circle and learn how to apply them in these questions. Remember, sketching the diagram always help.

Special Mention:

Next week, we will start revision on linear law. Some of you will be coming back to classes while some of you prefer to stay online. For student attending zoom, DO PRINT the following graphs before lesson.

See you this weekend!

[S4 Chemistry PMCians]

What we did in 2 hours:

We were reminded on how a balanced chemical equation informs us about the mole ratio that reagents react in and the use of balanced chemical equations to determine limiting reagents (recall: if there is two quantities of starting reagents given to us, always determine your limiting reagent). We also reiterated the importance of the number of moles which allow us to interconvert between measurement units such as mass to volume.

What you take home:

You should be actively attempting your Take Home Package questions to apply what you have learnt in lessons to other top school questions.

Special Mention:

We will be embarking on Redox and Metals after this chapter on Stoichiometry. Here’s a quick infographic to help you recall the calculation of oxidation states, an important concept in redox!
