[J1] Lesson 24 (Forces + Graphing + Bonding & Gases)

[J1 Physics PMCians] Aceing Forces

 

What we did in 2 hours:

This week, we revised the concepts for an object to be in static equilibrium

We learnt how to use the 2 methods to confirm if an object is in Translational Equilibrium, and 2 techniques for Rotational equilibrium. We also reviewed the reason for Upthrust and how to calculate it.

Kudos to all our students – for you did well in attempting the challenging questions that were set!!

What you take home:

Forces Round 2 & Take-Away questions (solutions)

Special Mention:

Next week, we will help you ace Dynamics!! 

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.

 

Till we meet next week – stay safe and keep strong.

What we did in 2 hours:

Graphing Techniques revision! Graphing Techniques is a large chapter, spanning multiple parts. The lesson covered Conics, as well as Rational Functions, and we did a bit of warm up with Transformations.

 

Do remember to prepare equations in the formats as we discussed, to prepare and sketch the graphs efficiently! Additionally, the question types we covered are based on popular J1 promo styles, so use them as a reference for your revisions.

 

What you take home:

The take-away solutions are linked here:

Special Mention:

This week, we will carry on with the rest of Transformations, before moving on to some AP / GP revision.

What we did in 2 hours:

Our revision on Chemical Bonding begins. This is a huge chapter, which sees us through the 3 strong chemical bonds and 3 weak chemical bonds. We paid attention to intermediate bonding of ionic compounds, type of IMF between discrete molecules (through the use of concepts such as VSEPR theory and polarity of molecules), as well as factors affecting the various types of bonds to determine their relative strengths.

What you take home:

The solutions to the Test Yourself for Chemical Bonding is found here:

Special Mention:

Next lesson, we will complete Chemical Bonding revision, and begin The Gaseous State.

 

See you (online)!
