[J1] Term 2 Week 5 (20-26 Apr) Updates/ Debrief

[J1 Physics PMCians] Conservation of Linear Momentum & how it happens!!

 

What we did in 2 hours:

Moving on from Newton’s 2nd law, we introduced the concept principle of Conservation of Momentum, which is just an outcome of Newton’s 2nd and 3rd law. The class tried the various questions involving elasticinelastic and perfectly inelastic collisions. We concluded with a 4Q quiz and Kahoot!

What you take home:

1) Dynamics Daily Dose

Please download and print the Daily Dose for your personal revision. The answers and working are at the back:

Special Mention:

Next tutorial, we move on to a new but fundamental concept in Physics – the Conservation of Energy!!.  

Please ensure that you have completed watching the Work, Energy, Power Lesson 1 before our tutorial, under the course : JC1 Physics Lesson 16 (20 – 26 April 2020).

Till we meet again, have a blessed week!! 🙂

What we did in 2 hours:

Webcast:

Wrapping up AP GP, we move on to get acquainted with summation and the Sigma notation. We get familiar with how to use it and also relate it to the AP and GP concepts.

LIVE:

We covered some applied AP GP questions, some of which are a bit more complicated than usual. Modelling type was practised, lets train ourselves to set up problems and observe any familiar patterns!

 

What you take home:

In this current learning format, your materials will be uploaded to your folders at pmc.sg/lecture , so do check regularly.

Special Mention:

The webcast this week will cover the Method of Differences, our final applied part of Sequences & Series. The LIVE lesson will mostly be on summation notation, so do familiarise yourself!

 

See You (online) and Stay Healthy!

[J1 Chemistry PMCians] Let’s get energised!

 

What we did in 2 hours:

This week, we have completed all our ten definitions of enthalpy changes, and went on to investigate how we can calculate enthalpy changes through the use of energy cycle diagrams and the application of Hess’ Law. This is the hardest part about this chapter, so the only way to be better is to practise, practise, practise!

What you take home:

The solutions to Everything you need to know series to Chemical Energetics is found below:

Special Mention:

In the next lesson, we will continue to explore the use of Hess’ Law and some shortcuts to make our lives during exams easier.

Stay strong!
