Basic scale

basic quantity is the unit quantity specified in advance and can not be derived from other quantities.

Point scale is used as a base for other quantities mendefinikan (derived quantities). Scale nature of the subject is free of other basic quantities, or the principal amount of one does not depend on size of other subjects, both dimension and magnitude.

In addition to the main scale, there are two additional quantities are not dimensionless.





characteristics of Materials and constituent

Chairs, tables, television, and other items in your house is made from materials different. Wood, plastic, cloth, and glass are some building block of household furniture in your house. Each of these materials have certain characteristics, which vary between one and another. To identified several types of materials based on constituent structure, consider The following explanation!

Types of Materials Based on constituent structure
You would never follow kegitan camp held by school. By the time you set up a tent would need a rope to a tent it can stand upright. Boy Scout activities, the rope can also be used to make a stretcher with the help of two sticks. In addition, the rope also widely used for people who climb or fall from the cliff.
The materials that make up the rope is fiber. Fiber is the part basis of the rope and form a chain that can not be separated anymore. Examples are the strings, nylon, and fibers. String is derived fiber of plastic, for example strings for flying kites and string to fishing. Nylon is a man-made fibers, while fibers are fibers thatderived from the base of the stem of palm trees.


Combination of several fibers to form yarn. Examples yarn mattress sewing and yarn. Sewing thread and yarn made of fiber mattress cotton. The rope is a combination of beberpa a single thread. For example rope and plastic rope.

The rope is composed of fibers and yarns have a flexible and powerful nature. Because of its nature it easily wrapped around the rope and made into a knot. Besides nature flexible cord is also very strong that can be used to draw objects, as when a car or truck broke down.
Carpets, curtains, rug, clothing, and pants are objects that composed by sets of strings, ie string. Shirts and pants that we use comes from the fabric which is also composed of a collection of threads. Objectsothers, such as chairs, tables, windows, cupboards, etc. are also composed of objects different types.

Application of Materials Based on constituent structure
Materials that make up an object affects the body uses it. Bamboo can be used to make fences and chairs or if woven can be made booth. Rattan can be used to manufacture materials chair. However, not all chairs are made of wood, bamboo, or rattan. Plastics can also be used to make chairs and objectsanother. Building block of this object would affect its usefulness. Chair made of wood or rattan has a different character with a chair plastics.

Structure building block of an object would affect the use of material. For example, a chair in wooden schoolinstead of plastic. This course is intended to make the chair more durable, not easily broken or damaged. Similarly, the ruler used by mother or father of a teacher at the school are made of wood instead of plastic likeyou use for school.

Particle Motion

The distance between the gas particles farther than the distance between the liquid particles, while the distance between the liquid particles further than the spacing between solid particles.

Solids when heated, the energy particles of matter increases. At that time, solid particles move faster and the distance between particles even further so that the particles move more freely. On condition that, being a substance changes from solid to liquid.

Form Substances

Has three states of matter, namely solid, liquid and gas. Solid and liquid has mass and occupies space. These substances can be measured using the mass balance. 
Gas can also be measured by its mass, although very small. This also proves that the gas has mass. 
Based on the volume and shape, each substance has different properties. Possess solid volume and shape remain. Liquid has a fixed volume and nature of the changing shape. As for the gas properties change volume and shape change.



Substance can exist in three states, namely solid, liquid and gas. Some changes in the form of the substance can be explained as follows:









The smallest part of matter that still has a substance is called a particle. particles are often called molecules.
