In form 4 chapters, there are some important physics principle need to be mastered now b4 its too late. In each principle u must understand and able to do the following:
i.state the principle
ii. relate the factors that affect the principle
iii. understand the experiment (if available)
iv. the calculation part (if available)
iv.describe its application
Among those requirement, most students have been focusing too much on doing calculation. Bila jumpa formula jer, u guys are keen to do exercise on solving the mathematical problems.In the end u 've ignored one of the most important part, i.e its application. Usually the application part will be asked in the paper 2 either section A, B or C. The application part requires u to explain almost everything on how the things work based on relevant physics concept.
As a continuation from our previous discussion regarding hot air balloon, i want u to recall about its famous physics principle i.e Archimedes Principle. Watch this video for a better understanding about it...
If u've gone through the videos or revised this principle through reference books, make sure that u are able to describe the following applications by relating it to Archimedes principle:
1. submarine
2.hydrometer
3.cargo ship
4.hot air ballon
5.plimsol line and others
U may discuss about it with others in the comment section or the chat box. Enjoy your revision :)

Archimedes & Hot air Balloon
Ok..today i'm gonna answer my previous question on hot air balloon...some of u did answer it with some common sense on why the balloon rises easily in the early morning..
However in SPM, using common sense only isn't enough for u to get full mark..u must relate your answer with relevant physics concepts or principles.
...Physics concept??? What physics concept???
To make it simple, if hot air balloon rises, it needs a larger force pulls it up to counter its weight that pulls it down.
In SPM, this upward force is called buoyant force..atau in bahasa melayu we call it 'daya apungan'.Thats why the balloon can rise & float, coz ada 'force' yang tolong mengapungkannya. So the question is how to have this 'daya apungan' big enough to pull the baskets??
This buoyant force concept comes from a famous principle called 'Archimedes Principle'.Now, lets analyse how can we can relate it to this principle...
Archimedes Principle
Mr Archimedes states that...
If an object is fully / partially immersed in a "FLUID" the buoyant force is equal to the weight of the fluid displaced.
The term 'fluid' is used in the statement above..do u understand what fluid is? Senang cerita fluid ni adalah benda yang mengalir such as liquid & gas. In the case of hot air balloon, the object is the balloon. The fluid is the surrounding air ( udara) which is the one that was displaced.
THEN according to archimedes principle..we can deduce a formula like this:
Buoyant force = Weight of AIR displaced ( since W=mg)
Buoyant force = mg [(mass of air displace ) x (g)]
(since density ρ = m / V , so m = ρV)
Therefore,
Buoyant force = ρVg (air displace)
( ρ =density, V =volume)
From the formula, Buoyant force depends on the air density.
We can say that the bigger the density, the larger the buoyant force...
Ok this is the key factor to determine the right time for hot air balloon to take off .
..
Early in the morning, the air is cooler than in the afternoon. Cooler air is denser than hot air, i.e it has higher density. According to the relationship above, cooler air will result in bigger buoyant force. So the balloon has a larger buayant force to counter its weight. Thus the balloon will be easier taking off in a cool temperature rather than during hot tempperature. This explain why the organiser choose those two session, i.e early in the morning and in the evening.
Another point,when buoyant force is bigger, so we can carry more loads. Thus if the same no of 'burners' is used,more participant can be carried in the morning compared to afternoon.
Please noted this discussion is only concerned about the air density surrounding outside the balloon.
There are many other factors that allow the balloon to rise faster..so its your task to figure it out yourself :)
haha ni ada sikit clue, cuba u all masak maggi, then observe..asap dia naik ke turun :) ????
tapi kalau bukak freezer peti ais cuba tgk asap dia naik ke turun??
May b u can also try this activities at home..

Hot Air Balloon in Putrajaya
Recently i managed to catch a closer look on hot air balloon event which was held in Putrajaya. Unfortunately when my turn was almost there, the lightning flashed and the sky rained on us. Well at that time i would rather stay on the ground rather than risking my life a close encounter with the lightning :).. In the end the organiser had postponed the balloon from taking off .
Here is some of the interesting shots to be shared during the event..
The picture looks interesting rite :)...anyway i have some questions to all of u. During the event, the organiser allowed spectators to ride the ballon only for these 2 sessions, i.e
i. as early as 8am to 11am, or
ii. ..from 6pm to 8pm
Haha..by using relevant physics concept :), can u explain why these two session are chosen? Why can't it be at 12pm, 3pm or 4pm?
Lets share your answer in the comment section..let's see who can give the most accurate answer :)

Superconductor
Superconductor is one of the most fascinating features in physics. This concept allows a bullet train to float a few milimetre on its rail, causes less friction to make it moves at 'super' speed. However we're unlucky coz in SPM we wont study abt it in detail.If u wanna pursue your career in electronis,electrical or mechanical engineering.. i think its good to be exposed about it as early as possible.
To understand superconductor, u must understand the word conductor itself. Conductor is like a wire which can conduct electricity. Usually a wire has resistance. Resistance comes from the word, 'resist'..i.e it resists the flow of electrons or current. Different wires has different resistance.But bear in mind, not all conductors are wires.
So..how about superconductors??
Under low temperature, the resistance of a conductor decreases. But under extremely low temperature, some conductors has almost NO resistance...i.e it has ZERO resistance. If this condition is achieved, the conductor now has transformed itself into Superman :) ops!!...it supposed to be SUPERCONDUCToR.
Kalau nak senang faham..bayangkan superconductor ni mcm sebatang highway ..
Tapi katakanlah highway tu sekarang bapak u yang punya :)
So bila hari raya, disebabkan highway PLUS tu bapak kita yang punya. So kalau u jalan kat highway tu takde siapa pun yg nak kacau..takde traffic jam..takde polis...i.e takde apa2 halangan. Kalau u nak main skateboard kat situ pun boleh :)
Senang citer kita kata highway tu takde "resistance". (ZERO RESISTANCE)
Kalau nak tau lebih detail pasal superconductor ..Wajib tgk video2 ni!!

7,987 SPM Candidates Excel
PUTRAJAYA, March 11 (Bernama) -- 7,987 Sijil Pelajaran Malaysia (SPM) 2009 candidates registered excellent results (A+, A, and/or A-) for all subjects sat for compared to 6,277 in 2008.
Education director-general Tan Sri Alimuddin Mohd Dom said of the total 214 candidates had excellent grades (A+) in accordance with the new grading implemented last year.
He said the new top grade was introduced as a higher grade than 1A to further detail a candidate's excellence.
"I am glad to announce that on the whole the achievements of the candidates this time is something to be proud of, exceeding the achievements of last year.
"The achievements of the candidates increased from the aspect of numbers obtaining excellent certificates (A+, A and/or A-) and passing all subjects sat for," he said when announcing the analyses for the SPM and Sijil Tinggi Agama Malaysia (STAM) 2009 examinations at the Education Ministry here Thursday.
He said 465,853 candidates registered for exams last year.
Alimuddin said of the 59,433 private candidates and candidates of private schoolS and agency-sponsored schools besides the Education Ministry, 41 candidates had excellent grades (A+).
He also announced that Gladys Tan Yee Kim from Sekolah Menengah Kebangsaan (SMK) Green Road, Kuching, Sarawak was the best student for SPM 2009 and Sekolah Menengah Sains Seremban, Negeri Sembilan as the best school.
He said of the 10 best students the other nine were Grace Kiew Sze-Ern (SMK (P) Sri Aman, Petaling Jaya, Selangor); Khadijah Ahmad Jais (SM Agama Persekutuan Labu, Negeri Sembilan); Akmal Hidayat Sabri (SMK Derma, Kangar, Perlis); Syamilah Mahali (Kolej Tunku Kurshiah Seremban, Negeri Sembilan); Lee Wei Ling (SMK Taman Melawati, Selangor); Nur Syuhadah Muhamad (SM Sains Tengku Muhammad Faris Petra, Kota Bharu, Kelantan); Lai Yin Kwin (SMK Tinggi Melaka, Melaka); Corinne Gunn Huey Min (SMK Taman Melawati, Selangor); and Hu May Khei (SMK Convent, Taiping, Perak).
He said the other nine best schools were Kolej Islam Sultan Alam Shah, Klang, Selangor; Sekolah Berasrama Penuh Integrasi (SBPI) Gombak, Jalan Sungai Pusu, Gombak, Kuala Lumpur; Sekolah Tun Fatimah, Johor Bahru, Johor; Sekolah Menengah Sains Alam Shah, Kuala Lumpur; SBPI Rawang, Selangor; Sekolah Menengah Sains Muar, Johor; SBPI Temerloh, Pahang; SMK Infant Jesus Convent, Johor Bahru, Johor and Kolej Tunku Kurshiah Seremban, Negeri Sembilan.
Alimuddin said of the 406,420 Education Ministry candidates who sat for the exam, 364,046 (90.8 per cent) obtained the SPM certificate compared to 347,443 (90.8 per cent) in 2008.
"Eventhough the percentage is the same there has been an increase in the number of candidates of 16,603. The achievement is stable as the previous year.
He said 199,155 (49.6 per cent) candidates passed all subjects taken compared to 181,419 (47.4 per cent) last year.
He said of that total 68,131 (17 per cent) had at least grade C for all subjects compared to 60,902 (15.9 per cent) in 2008.
"This achievement shows a good increase. However, the number of candidates who failed or obtained G grade increased, that is 4,626 (1.15 per cent) in 2009 compared to 2,589 (0.67 per cent) in 2008," he said.
Alimuddin said 538 candidates who had special needs for various disabilities sat for the 2009 SPM exam compared to 481 candidates in 2008 and of that number 251 (51.9 per cebt) obtained the SPM certificate compared to 208 (47.8 per cent) in 2008.
He said two candidates with impaired eyesight got four A+, three As and four A- for 11 subjects sat for and one had four A+, three As and three A- for 10 subjects sat for.
"Two more candidates with various handicaps did very well when both got eight A+, two As for 10 subjects taken," he said.
He said the achievements of urban and rural students was better compared to the previous year as 5,942 urban students and 1,243 rural students did well in all subjects compared to 4,750 urban students and 989 rural students in 2008.
He said the divide between urban and rural students was narrowed in performance in core subjects like English, Science and Moral Education.
Alimuddin said however efforts to reduce the performance divide between urban and rural students needed to be increased especially in Bahasa Melayu, History, Mathematics and Islamic Studies.
He said based on average school grades, 66 schools were in the Excellent category, 278 (Good), 1,654 (Satisfactory) and 143 (Potential) and this showed that the efforts of the ministry to enhance schools' performance was successfully implemented.
