Dimanakah letaknya kunci itu?

Di Manakah Letaknya KUNCI Itu?

Kejayaan merupakan sebuah mahligai indah yang terkunci , di dalamnya memiliki 1001 nikmat . Hanya manusia tertentu sahaja yang mampu membuka pintu mahligai itu . 

" kunci kejayaan ada di tangan anda "

Setiap manusia yang dilahirkan di muka bumi ini adalah meruakan khalifah yang bakal mentadbir bumi Allah ini pada segenap empat penjuru yang tiada sempadan ini. Pesoalannya adakah kita mampu membuat sedemikian? "Tepuk dada tanya iman "
 pada hakikatnya kita mampu untuk mentadbir bumi ini sekiranya kita memeberi komitmen yang tinggi dalam menjadikan diri sebagai manusia yang berguna . Itu merupakan kunci pertama untuk menempa kejayaan kelak . Kejayaan tidak akan datang kepada mnusia yang leka . 
Akhlak yang positif mampu mengubah dunia ke arah kegemilangan. Oleh itu di sini dapat disimpulkan perubahan diri bermula daripada diri sendiri 
"Allah tidak akan mengubah sesuatu manusia  itu , kecuali manusia itu mengubah dirinya sendiri"

"Hidup adalah gabungan antara bahagia dan derita. Ia adalah menguji keteguhan iman seseorang. Malangnya bagi mereka yg hanya mengikut kehendak hati tidak sanggup menerima penderitaan."
Begitu juga dengan kunci yang dimaksudkan , dalam kehidupan ini kita boleh untuk membuat keputusan sendiri .Hidup di muka bumi ini hanya ada dua jalan sahaja yang boleh untuk kita pilih iaitu kebahagian atau kesengsaraan .
Bagi manusia yang sentias brpegang teguh pada iman dan taqwa sesungguhnya Allah sentiasa memberi petunjuk kepada golongan ini
Tetapi bagi mereka yang lalai sesungguhnya mereka telah menyeksa dan menzalimi dirinya sendiri.

"Gantungkan azam dan semangatmu setinggi bintang di langit dan rendahkan hatimu serendah mutiara di lautan"

Hidup di muka bumi Allah yang fana ini pasti ada pancaroba dan kemelut yang harus kita semua sebagai hamba Allah untuk menghadapinya.
INGAT !
setiap dugaan dan cabaran yang Allah kurniakan kepada kita adalah untuk Allah menguji sejauh mana tahap keimanan kita terhadap-Nya.
Oleh itu , dapat dibuktikan disin bahawa setiap kunci kejayaan itu sudah ada pada diri kita , dan kita akan membentuk kunci itu untuk kita menggapai apa yang kita inginkan .

Kunci Kejayaan merupakan tonggak kehidupan
Kunci Kejayaan itu Ada pada Anda.

Oleh itu, kita haruslah sentiasa menerapkan segala keperibadian yang mulia agar kunci yang ingin dibentuk dapat bihasilkan dengan sempurna . Justeru itu, pemikiran yang positif merupakan tonggak utama sebagai landasan yang boleh membimbing kita sebagai khalifah di muka bumi ini untuk bergerak ke jalahn yang diredoi dan dirahmati oleh Allah SWT.
"Kecemerlangan adalah hasil daripada sikap yang ingin sentiasa melakukan yang terbaik."

Types of Forces

A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.
 
Contact Forces
Action-at-a-Distance Forces
Frictional Force
Gravitational Force
Tension Force
Electrical Force
Normal Force
Magnetic Force
Air Resistance Force
 
Applied Force
 
Spring Force
 

These types of individual forces will now be discussed in more detail. To read about each force listed above, continue scrolling through this page. Or to read about an individual force, click on its name from the list below.

 

Type of Force
(and Symbol)
Description of Force

 

Applied Force

 

Fapp
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.

Gravity Force

 

(also known as Weight)

 

Fgrav
The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found by the equation:
Fgrav = m * g
where g = 9.8 N/kg (on Earth)
and m = mass (in kg)
Normal Force

 

Fnorm
The normal force is the support force exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. On occasions, a normal force is exerted horizontally between two objects that are in contact with each other. For instance, if a person leans against a wall, the wall pushes horizontally on the person.

Friction Force

 

Ffrict
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Thought it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion. Friction results from the two surfaces being pressed together closely, causing intermolecular attractive forces between molecules of different surfaces. As such, friction depends upon the nature of the two surfaces and upon the degree to which they are pressed together. The maximum amount of friction force that a surface can exert upon an object can be calculated using the formula below:
Ffrict = ยต • Fnorm
The friction force is discussed in more detaillater on this page.

Air Resistance Force

 

Fair
The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude (and due to the fact that it is mathematically difficult to predict its value). It is most noticeable for objects that travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas. Air resistance will be discussed in more detail in Lesson 3.

Tension Force

 

Ftens
The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.
