Extra Questions on Linearisation

 

We are always trying to put the equation in to the form:

y = mx + c

 

 

a) p = mv

p/v = m

p(1/v) = m

m = p(1/v)

So to get a straight line graph we will plot m against 1/v

Gradient will be p.

c = 0
Therefore intercept will be (0,0)

b) T = 2π √(L/g)

T² = 4π² (L/g)

T² = (4π²/g)L

So to get a straight line graph we will plot T² against L

Gradient will be 4π²/g.
Thus g can be found from g = 4π²/(gradient)

c = 0
Therefore intercept will be (0,0)

c) s = ½at²

s = ½at²

So to get a straight line graph we will plot s against t²

Gradient will be ½a
Thus a can be found from a = 2 × (gradient)

c = 0

d) n = (sin i) / (sin r)

(sin r)n = (sin i)

(sin i) = n(sin r)

So to get a straight line graph we will plot (sin i) against (sin r).

Gradient will be n.

c = 0
Therefore intercept will be (0,0).

e) 1/ƒ = 1/u + 1/v

(1/u) = (–1)(1/v) + (1/ƒ)

(1/u) = (–1)(1/v) + (1/ƒ)

So to get a straight line graph we will plot 1/u against 1/v

Gradient will be -1.

c = (1/ƒ)
Thus intercept will be (0,(1/ƒ))

ƒ can be found from ƒ = 1/(gradient)

Answers to Practical PR3

MarkSchemeS4P03_updated

Common Mistakes made were:

  • forgetting units in table headings

 

Graph

  • not labelling axes correctly (with units)
  • poor scales
  • not differentiating the two types of points
  • poor best fit curve
  • working for gradient not shown on the graph (large triangle and coordinates of end-points stated)

 

Three common shapes of graph are:

Your description of the graph m
ust allow the reader to differentiate which one you are referring to.

A increases as B increases.

C is directly proportional to D

E is linearly related to F.

Reminder:

Gradient = Δy/Δx

Resistance = y/x     i.e  R=V/I

y/x ≠ Δy/Δx (except for a straight line passing through (0,0).)

YDSP 2022

Dear Sec 4 students,

Invitation to Participate in the Young Defence Scientists Programme (YDSP) World of Science (WOS) Modules 2022

The YDSP WOS 2022 is now open for student applications.

There are 7 exciting WOS enrichment modules this year! The modules are specially designed for IP4 to IP5/JC1 students. To help you and your students better understand the modules, please refer to the attached file ‘YDSP WOS 2022 Module Synopsis’ for more details.

In view of the current COVID-19 situation and the safe management measures in place, the modules will be conducted via physical and/or virtual sessions. DSTA will continue to monitor the COVID-19 situation. If necessary, all modules will be conducted via virtual platforms. The final arrangement will be confirmed with the shortlisted students nearer the date.

A Certificate of Participation will be given to students who achieve 100% attendance for the modules. Please note that students may select up to three modules according to their preference. If selected, they will only attend ONE module.

Please take note of the dates of each module and ONLY apply if you are able to fully commit to the stated dates. In the event that you are selected for the module but decide to withdraw from the module due to any reason or fail to attend all the sessions, it may adversely affect future scholarship or programme application with DSTA.

Please also note that WOS 2022 is only open to Singaporeans.

Please click on this link to submit your application by 21 Jan 2022.

Advanced Physics (modified)Team-based Investigation Project (mTIP)

The scaled-down mTIP will now be conducted in Groups of 2 (from the same class) or done individually.

The project can be an experiment or research on a physics phenomena.

Both options will require submission of a report (PowerPoint Slides) and a presentation.

The Task

Option 1: Experimental Practical

Design and conduct an experiment to investigate any suitable physics phenomena of your choice.

You will need to plan an experiment and let Mr Shone know what physics equipment you wish to borrow from the lab – drop him an email ASAP.

 

Option 2: Research

Choose a topic of suitable difficulty  and suitable depth to investigate on your own.

The topic must not be something we have already looked at as part of the Advanced Physics syllabus.

 

The Presentation

The presentation must be between 10 – 15 mins and everyone in the group must present.

The Slides are likely to include the following to be covered within the stipulated time:

For Practical Projects

      • Brief literature review (theory)
      • Experimental setup and brief procedures
      • Results
      • Analysis
      • Conclusion
      • Brief reflections and key takeaways

For Theory Projects

      • Detailed literature review ( of the topic). You will not be expected to talk on every slide as there is unlikely enough time within the presentation period. Thus summary slides might be useful at points.
      • history of the discovery
      • background information on the key scientists involved

All presentation will end with a short Q&A session.

Final WA Update…

Hi!

You can only take your WA during your assigned Physics Lesson slot. You must complete the WA within 30 minutes. The SLS assessment will only be open for 40 minutes starting from the beginning of your lesson (giving you 10 minutes to manage any technical issues – if encountered).
ie
for 303 that means between 8:15am and 8:55am.
for 304 that means between 9:15am and 9:55am.
You are therefore encouraged to log in and start the WA at the very start of your lesson. (You’ll not see the WA before this time as it will not be ‘live’.)

Any problems during the WA session you can contact Mr Shone via ZOOM:

Meeting ID: 579 057 2617
