material: mass and energy

Chemical study of the matter. The universe can be divided into the material world and the world of energy. Matter into the author all sorts of things. Energy is the ability to conduct business. Energy is the cause of the change of material. Matter has mass and weight. Mass and weight are two different quantities. The mass of an object or material that remains. However, the weight of an object depends on the acceleration of gravity in accordance with the equation:

G = m. g

Where: G = weight
m = mass
g = acceleration due to gravity


every material has the energy. Energy is owned by materu divided into kinetic and potential energy. Kinetic energy is energy possessed by the moving material. Wind, water, and the speeding car has kinetic energy. Energy is owned by a material that is not related to the motion is called potential energy. The relationship of matter and energy expressed by the equation made by Albert Einstein

E = m. c2

Where: E: energy
m: mass
c: speed of light = 3. 10e8 m / sec

meteri properties are distinguished on physical properties and sifar kmia. Material manifestation of being solid, liquid and gas.
