Weight can be described as a quantity that represents the exerted force on particles by acceleration fields, especially the earth’s gravitational field on its surface. In SI units is expressed in regard to force while in Newton’s theory it is exerted to mass in regard to gravity. The standard unit for measuring weight is Pound (lb) and this is technically the force that gravitational acceleration [...]

Carbon is a nonmetallic element that is naturally abundant that is known to form the basis of many living organisms. Carbon is considered to be the fourth abundant element to be found in the world. In addition, carbon plays a major role in stability and health of the earth as a planet via the carbon cycle. The cycle is normally very complex and also illustrates an interconnection between the earth [...]

Overview Oil is a fossil fuel, which is formed from the deposits of organisms that were once living such as dead plants and animals. The formation of oil; a nonrenewable resource takes millions of years. Formation of Oil The oil used today took millions of years to create. It was formed when tiny animals and plants died and were buried at the bottom of either the sea or ocean. The dead organisms were [...]

Magnets are metallic materials, mostly steel or iron, which are used to attract other metals. The most powerful magnets can be created from special alloys of cobalt, aluminum, nickel, iron and copper. Metallic materials can permanently become magnets when they are inducted. Every known material is made of quite tiny particles that are known as molecules. The tiny molecules making up steel and iron [...]

Definition The basic meaning of matter is any substance that occupies space in addition to having Mass. Matter happens to be existent in four different states, which are liquid, solid, gas as well as plasma. Solid is distinguished by its ability to maintain structural integrity. They have a significant amount of rigidity and break only when put under considerable stress. The elements that make up liquids [...]

Definition Sound refers to the vibration or the wave caused by the motion of an object causing air molecules to make vibrations. The word sound is also used to mean the sensation that can be detected by the ears due to the rapid changes in the air pressure below and above the static value. The way sounds are detected can be presented using diagrams like sine waves. However the sound forms a longitudinal [...]
