[J1] Lesson 25 (Dynamics + Graphing & Sequence and Series + Gaseous State)

[J1 Physics PMCians] I’m gonna Ace Dynamics!!


What we did in 2 hours:

We revised the 2 main concepts in Dynamics. Each time we deal with a question involving forces, we always follow the same process:

1) draw FBD

2) indicate direction of acceleration

3) use net F = ma

We also relooked the principle of Conservation of Momentum, and how to solve both elastic and inelastic collisions!


Thank you also for giving us your feedback on whether you prefer to have classes Onsite or Online

Rest assured, we will cater to both groups, in the same timeslots. 

What you take home:

Dynamics Round 2 & Take-Away questions (solutions)


Special Mention:

Next week, we will help you ace Work, Energy & Power!! 

As you prepare for your Common Test, do make use of our Digital Library for your revision. Send your request to PMC Admin to sign up for the Digital lessons.


Enjoy the greater freedom in Phase 2 CB! 

See all of you very soon!!

What we did in 2 hours:

Our second lesson of Graphing Techniques revision covers the rest of transformation, including the Modulus graphs as well as the Reciprocal graph. We looked at how these graphs are done and also put up a set of streamlined steps to follow for the reciprocal graph. Keep practising to build familiarity!


Additionally, we kicked off some Sequences and Series with a few refresher questions on AP GP. Recap the basic ideas and simple applications, which we will build on more in the coming lesson.


What you take home:

The take-away solutions and Grade-A questions solutions for graphing are linked here:


Special Mention:

This week, we will be looking at more complicated AP GP application questions, as well as some Method of Differences.

What we did in 2 hours:

This week, we completed our revision on Chemical Bonding, which focuses on determining relative melting/boiling points and solubility for molecules through the identification of its IMF. We then completed our revision on Gaseous State, applying the ideal gas equations under various circumstances, and looking at how real gases deviate from ideality.

What you take home:

The solutions to the additional Structured Questions and Test Yourself are found here:

Special Mention:

Next lesson, let us revise the last topic on Chemical Energetics.
