[S4] Lesson 24 (Kinematics + Binomial Theorem + Periodic Table )

[S4 Physics PMCians]

What we did in 2 hours:

On the 13th and 14th June, the S4PH has come together to cover the following during our weekly zoom lessons: 1) Secret Enclosed Kinematics Concept 1 and 2, and 2) Kinematics Final Lap (20 MCQs).

Always remember:

1) To solve any question related to Kinematics, draw the v-t graph first as this graph gives the acceleration (gradient) and distance traveled (area).

2) To convert graphs, ask yourself the 2 questions: a) Is it +, – or zero? b) Is it increasing, decreasing or constant.

What you take home:

We will continue with Kinematics Revision L2 where we will do our thinking-aloud discussions 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.

With you, as usual,

The S4PH Tutors

What we did in 2 hours:

We started on Binomial Revision. We use binomial theorem to expand

(a + b)n for a positive integer n. Since there is a pattern in binomial expansion, we can identify and find a particular term using general formula.  We practiced on how to derive the general term using the formula and law of indices. We also tackled question where n is unknown by changing it into algebraic expression that can be solve easily.

What we did in 2 hours:

We have completed our revision on Periodic Table trends and used the big idea of the relationship between distance of valence electrons from the nucleus and electrostatic forces (hence ease of losing/gaining electrons) to explain reactivity of elements in Group I and VII. We also extended our understanding to data based questions and unique concepts such as electronegativity and ionisation energies.

What you take home:

We have kickstarted our revision on Stoichiometry and appreciated how moles can be interconverted between units. Do take some time to recall stoichiometry concepts such as limiting reagents and empirical formula for our lesson this weekend.
