[S3] Term 1 Week 6 (10-16 Feb) Updates/Debrief

[S3 Physics PMCians]

 

What we did in 2 hours:

Last lesson, we focused on the basic concepts of Kinematics, and introduced terms such as displacement, velocity and acceleration. By now, most of you should be familiar with those terms, how to determine their direction and also how to derive them from a kinematics graph (whether its a displacement-time or velocity-time graph).

Kinematics is traditionally a challenging topic for many students. We went slow in the 1st lesson so we can go faster later. Lets win this race together!

 

What you take home:

You can download this simulator on kinematics to better understand the concepts. Tinker with the values and see how velocity and acceleration affects the motion of the man.

Special Mention:

Next lesson, we will be focusing on how to solve problems with graph drawing. In the meantime, stay safe and keep on going (for kinematics)!

What we did in 2 hours:

We had summed up all the concepts we need to know for Sum/Product of Roots. Please practise more on your own to familiarize the concepts, together with all the useful identities 😉

Next, we recalled solving Linear Inequalities and Quadratic Equations from lower sec. Continuing from these topics, we learnt how to solve Quadratic Inequalities with simple tricks!

 

What you take home:

Solutions to Sum/Product of roots Test:

Please try Take Away Questions (Quadratic inequalities):

Page 112, Question 1 to 3

Solution to Take Away questions will be uploaded next week.

 

Special Mention:

We will continue to learn another behaviour of quadratic functions. By analysing its discriminant, we can identify the number of solutions to these equations.

What we did in 2 hours:

In preparation for Weighted Assessment season, we kickstarted our Topic Mastery Quiz on Separation Techniques, Kinetic Particle Theory, Atomic Structure and Chemical Bonding with both team and individual challenges. All classes are currently on track to score an A!

 

What you take home:

Continue to take the time to recap the chapters that we have completed and feel free to drop us a text if you have any queries regarding school or PMC work!

 

Special Mention:

We will end our Topic Mastery Quiz next week and begin on mole concept and stoichiometry – a HUGE topic for chemistry.

Trivia – Did you know how the mole came about? Watch this video to find out:
