| Key Ideas |
| 1. There are two types of electric charges: positive and negative charges.
2. Like charges repel, unlike charges attract. 3. Electric charge is measured in coulombs (C). 4. Electrostatic charging of insulators by friction involves a transfer of electrons. 5. Electrical insulators do not conduct electricity because they do not contain mobile charged particles. 6. Electrical conductors are able to conduct electricity because they contain mobile charged particles (electrons). 7. Electrical conductors can be charged by induction. 8. Electrical insulators that are charged can be neutralised (discharged) by heating or exposure to humid conditions. Electrical conductors that are charged can be neutralised by earthing. 9. During electrostatic charging and discharging, only electrons are transferred. 10. An electric field is a region in which an electric charge experiences an electric force. 11. The direction of the electric field is the direction of the force acting on a small positive charge placed in the field. 12. Some hazards of electrostatic charging are lightning, and electrostatic discharge near flammable substances. 13. Electrostatic charging is used in photocopiers, electrostatic precipitators to reduce air pollution, spray painting to produce an even coat of paint. |
IMPORTANT STUDY POINTS
| 1. | Be aware of the formula Q = nq to calculate the number (n) of charge carriers given the the charge (q) on one particle and the total amount of charge (Q). |
| 2. | As 1 C is a large amount of charge, must know how to use or convert units such as millicoulomb and microcoulomb. |
| 3. | Must know the difference between how insulators and conductors are charged, and how they are discharged, and be able to explain these processes only in terms of the transfer of electrons. |
| 4. | Must know the difference between what happens when an insulator touches a charged object and when a conductor touches a charged object. |
| 5. | Must know the correct sequence for producing two similarly charged conductors, two oppositely charged conductors and a single charged conductor. |
| 6. | Must be able to define electric field and draw electric field patterns. |
| 7. | Be able to describe the dangers of electrostatic charging. |
| 8. | Be able to describe how electrostatic charging is used in photocopiers, precipitators and spray painting. |
Hope the above helps.

Study Tips: O-Level Physics Chapter 1- Measurement
Dear students,
If you want to master Physics chapter 1 Measurement, you must make sure you have understood the following Physics concepts and have perfected the following skills:
- Memorise the 7 base quantities and their units.
- Memorise the prefixes and must know how to convert from one prefixed unit to another eg. 10 dm = ? km.
- Must know how to convert to standard form with 2 or 3 S.F. Please note Physics calculated answers cannot be to 1 or 4 S.F. or more.
- Must know how to convert from composite unit to another eg. 72 km/h = ? m/s and vice versa. Please note 1.0 g/cm3 = 1000 kg/m3.
- Must know the Order of Magnitude of the sizes of common large and small objects eg. the height of a mountain is about 103 to 104 m and the diameter of an atom is about 10-10
- Must know and compare the Measuring Range, Precision and Common Usage of Measuring Tape, Metre Rule, Vernier Calipers and Micrometer Screw Gauge (refer to point 5 of Key Ideas above).
- Must know how to read the main scales of the vernier caliper and the micrometer as well as the zero errors to get the corrected reading. Corrected Reading = Observed Reading – Zero Error.
- Must know how to derive or measure the period of a pendulum. Good to know the ticker tape timer and the meaning of frequency.
You must practise the above knowledge and skills on both past year MCQs as well as the longer Paper 2 questions.

Attend our Physics Distinction program if you wish to learn Physics topics in advance and be given challenging questions to solve. Lots of thinking and questioning in every lesson. You will be exposed to tough questions from top school papers and past year papers. Join this program if you consistently scored B4 or above in your past Physicstests and exams, or you are passionate about Physics.
Attend our Physics Improve program if you wish to revise and even relearn the key Physics topics and concepts. Not all Physics topics are equally challenging or fundamental; some Physics topics have heavier emphasis in exams, some are conceptually harder and some must be fully understood before others can be mastered. Join this program if you want to learn HOW to study Physics. Join this program if you had consistently scored C5 or below in your previous Physics tests and exams, and now you are SERIOUS about improving your Physics grades

Tips on how to Excel in Integrated Programme
The challenges of the Integrated Programme may be overwhelming for many of us, especially for those of us who are not well informed about the expectations that the school has for the students. This is a guideline on the mindset you must have, and steps you can take to excel in the IP system.
- Humble yourself
For many students who have entered the IP system, you would have scored at least 250 cut off points and above, making you the top 10% of the P6 cohort. Most students of your calibre would also have been top students in your individual primary schools, enjoying years of praise and accolades bestowed upon you by teachers and parents alike. In IP schools however, you are a dime a dozen, and the “miracle” that you pulled off in PSLE may not work as well as you think it will from Y1 onwards. Secondary school education is about discipline and practice, unlike PSLE questions. Humble yourself and be open to learning new things, as well as consulting your teachers and even your peers. You are in a new world now, with many people who may be more academically gifted than you. Seek help whenever necessary and keep an open mind.
- Be proactive
Learning never ends in the IP system. Unlike Express stream, some IP schools may not have an official textbook or guideline to follow, and teachers use their personal notes and base their syllabus off their own judgment. Being proactive allows you to anticipate such challenges and prepare for them before it becomes disastrous. Consult your seniors, and read deeply into topics that are taught. You will not find a guide in the O-level texts, but you can use them for practice before you are taught that certain topic. The school expects you to learn ahead, and you might be surprised to find that many of your peers are doing so during the holidays. Be proactive and don’t idle away your time.
- Learn smart
I have lost count of the amount of students I have seen struggle with the IP system because they hold on to the idea of rote learning and memorization. Unless you have a photographic memory, memorization will not serve you well. On the contrary, it will sabotage your grades. The IP system is about critical thinking, and often poses open ended questions. However, you can spot certain trends, and work more on such problems in anticipation of them coming out in exams. Learn what’s on your formula sheet, and only remember equations that are not on it. Take note of what teachers emphasize on during lessons and tutorials. Don’t blindly memorize, instead, link the information to each other and understand how they interact. Make efficient cheat sheets and short notes on your own. Another pro tip, the IP syllabus typically likes to omit or test less of what is not in the A-levels, so you might want to proceed with that in mind.
- Plan ahead
Plan your time well, and do not procrastinate. Attend to your assignments, homework and project work immediately as you might not get the chance to do so. This is because there can be events such as SYF, bringing about extra CCA sessions, leaving you drained and tired. Teachers can suddenly assign new projects or heavy workloads without coordinating with one another. Surprise quizzes may be conducted. There is a reason for this, and it is to prepare you to be a leader in a volatile working world. Plan ahead, do not procrastinate, and put in a consistent effort every single day. Remember, your score is determined over the year, not on one single exam.
Lastly, try to have fun in school. There are many great opportunities for you to take part in and show your leadership skills, but at the same time, you can make many great lifelong friends. Even as a working adult, I still keep in close contact with most of my friends from IP, and we are still inspiring each other to improve and grow together.
