Salam Aidilfitri

Bila tiba 1 syawal, kita kena beraya jugak..

Bila kena study biar sampai result jadi gempak ;)

Salam aidilfitri untuk semua..

LESS is MORE

Today i'm gonna share with u  tips on avoiding mistakes while doing calculation type of question.
Common habit among student once they attempt calculative questions, they simply grab a calculator & start to press the button like playing PSP. They don't bother to highlight or jot down anything. This habit can cause u to do careless mistakes, especially if u forgot to change its figure into SI unit.
So for this purpose, i'm sharing u a technique that can minimise your mistakes.
This technique is called LESS..i.e u need to carry out these 4 steps;


1. List down and highlight all the information or figures given( check its unit as well)
2. Equation = choose the right equation/formulae
3. Substitute the figure into the relevant equation
4. Solve the equation..then baru press your calculator :)

For example:
A car traveling with a velocity of 10 m s^-1 accelerates uniformly at a rate of 3 m s^-2 for 20 s.   Calculate the displacement of the car.


1.list down the information: u=10 , a=3, t =20
2. Choose the equation..   (v² = u² + 2as)  or (s = ut + ½ at^2)...
you are not provided with v, thus most suitable is (s = ut + ½ at<sup>2)


Then substitute and solve the equation
s= 10(20) + (1/2 x 3 x 20x20)
 = 800m</sup>

If u apply LESS technique step by step.., i'm sure u'll grab MORE marks :)
just enjoy your revision during this festive season :)

Are u weak in electronics?

Do u still have problem to understand this topic??

Do u know which  favorite electronics topic for this year??

Physics Application: Electric Bell

Today's tips:

One important aspect in studying physics is the ability to apply & relate each physics concept. In SPM application part is vital as it always being asked in paper 2. You are expected to explain certain physics application such as the working principle of an electric bell. Usually there are 4 marks allocated for this type of question. However to explain it, u must fully understand the physics concept being applied. In the case of electric bell, we apply the concept of electromagnet.

Generally to understand basic concept of electromagnet, we must appreciate that every time current flows in a wire, magnetic field is produced. If the wire is coiled around soft iron, this causes the soft iron to be magnetized and become a temporary magnet. Once it becomes a magnet, it has the tendency to attract any magnetic materials such as iron armature in the bell.

Once u understand the basic concept, then u must practise to explain the working principle of an electric bell. Why dont u take a reference book,watch this video.. try to undertand and explain how it works ..





There are many other application of electromagnet such as relay switch,telephone ear piece, circuit breaker etc. Just make sure u are able to explain all of them.  

Form 4 Physics Law

Today's revision tips...
to improve your physics understanding, its a must for u to master all the physics law that u learn in SPM. U must also be able to relate & apply its formula. It will be helpful for u to answer both paper 2 & 3. For this purpose i summarised some physics law for form 4 topics only.  Ops..before some of u might ask.."How about list of form 5 physics law"??? Well there are only three physics law under form 5 topics..
..why dont u take out your refrence book & do some digging ..
anyway enjoy your revision :)..

F4 Physics Law

SPM Physics Definition

Today i'm going to discuss on SPM physics definition that can come out in paper 2 section A, B or C. Although there are a lots of definition need to be memorised, in average only 3 to 4 definition will be asked in the exam. Each definition contributes one mark only. If u are aiming for A+, u cant afford to loose too many marks. So its up to u, whether u want to grab all the marks on definition or  to 'sedekah' some of them :)

Some definition can defined straight forward by referring to its formula. For example, pressure can be defined as Force acting per unit area ( P=F/A) or resistance can be defined as ratio of potential differnt over current (R=V/I).

However please be careful because not all definition can be defined based on its formula. For example u can't define potential different by using V=IR. If u say that potential different equals to product of current and resistance, u 'll lose the mark. In fact to define it, u should refer to its fundamental equation, i.e V=E/Q. Thus potential different is defined as 'energy needed to move a unit charge from one point to another'.

Some of the definition does not belong to any equation. For example elasticity is defined as 'the property of an object that enables it to return to its original shape after an applied external force is removed' 
This kind of definition will be easier to memorise  if u fully understand the keyword used to describe it. Basically once u can understand the physics concept being discussed, its much easier for u to memorize the definition.

You have only few months before SPM. Well, there's still time for u to revise all of the definition in SPM. Hopefully this post will give u some rough idea to deal with it.
All the best :)

Semangat Ramadhan

Lama rasanya tak update blog ni, hmm sempena bulan mulia ni terpanggil untuk kembali menyumbang buah fikiran bagi membantu mereka yang memerlukan. Rasanya belum terlambat utk mengucap salam ramadhan al mubarak utk semua. Begitu pantas masa berlalu, tau-tau ramai yang kecut perut tatkala radiasi 'SPm' mula terasa bahangnya. Teringat pesan Nabi yang bijaksana, "hargailah masa lapangmu sebelum masa sibuk". Tapi apa nak buat, memang lumrah ramai yang leka bila waktu lapang..hanya mereka yang faham hakikat masa sahaja dianggap orang yang beruntung.

Yakinlah bahawa bulan ini penuh dgn barakah. Kita tidak perlu makan pagi,tengahari atau petang. Jika pandai mengurus masa..kita ada kelebihan disitu. Kita punyai masa yang agak berlebihan untuk belajar. Sesudah atau sebelum sahur juga boleh dimanfaatkan untuk ulangkaji....Oh tapi, masalahnya badan semakin letih. Otak semakin sendat dgn maklumat yang separuh masak. Masihkah ada sinar dan harapan untuk mengubah sesuatu yang hampir mustahil???

Oh sudah tentu ada..tetapi hanya yang berfikiran positif sahaja layak untuk melakukannya.

Harus faham bahawa ramadan ini bukanlah masa untuk merasa longlai tatkala menelaah prinsip Archimedes. Bulan in juga bukanlah masa utk merasa lesu tatkala pening memahami hukum Lenz. Mengapa harus rasa letih..kita bukan disuruh berperang secara fizikal. Walhal para sahabat ulung di zaman nabi telah membuktikan kerana ruh ramadan mereka berjaya dengan cemerlang di medan Badar yang pada mulanya hampir mustahil untuk menang. Mereka juga mungkin rasa lapar dan dahaga. Namun,kenapakah mereka berjaya?? Sesungguhnya mereka adalah manusia hebat, berdisiplin, bersemangat dan yang terpenting mendapat rahmat serta pertolongan ajaib dari yang Esa.

Oleh itu usah rasa ragu pada kejaiban ramadan. Kuatkan semangat dan tenaga untuk memecah tembok kebuntuan yang sudah terlalu lama mencengkam. Banyaklah memohon dan bersujud dgn rasa rendah diri padaNYA. Pohon juga kemaafan pada guru yang mungkin sering dicondemn' tatkala diri sendiri tidak bersunguh2 untuk faham. Harapnya redha Tuhan dan redha guru akan memberi cahaya baru.Maka akan cair aura mazmumah dan akan terang hati yang bakal menyuluh akal. Mudah-mudahan semangat ramadan mampu memberi sinar walaupun ketika di penghujung jalan.
