The science of matter is called chemistry. It is the study of matter, chemical reactions, compositions, structures and properties. Chemistry is a form of natural science.
Aristotle's definition of the four elements of fire, water, earth and air in classical Greece was the first time a chemical hypothesis was introduced. Since then, chemistry has evolved into multiple branches that include biochemistry, physical chemistry, organic chemistry, inorganic chemistry and analytical chemistry. Chemistry has been credited as a bridge between physics and natural science, and it explains some phenomena, such as the rusting of iron and the efficiency of the clean-burning fuel propane.Learn More
According to Concord Consortium, pith-ball, gold-leaf, and needle electroscopes measure electric charges using Coulomb electrostatic forces. Pith-ball electroscopes use attraction as a measure of charge, while gold-leaf and needle electroscopes use repulsion. These early instruments helped scientist understand and measure electric charges and polarity. Today they serve primarily as demonstration instruments.Full Answer >
Some examples of luminous objects are a burning candle, a light bulb, the sun and other stars, fluorescent materials and tube lights, among other things. Any object is considered luminous if it emits its own light, either through stored energy or energy supplied to the object, which contrasts with non-luminous objects such as the moon, wood, plastics and metals; these objects merely reflect light instead of providing their own.Full Answer >
An object is said to have uniform velocity if the direction of motion and the rate at which the object changes its position is constant. In other words, an object with uniform velocity continues to cover the same amount of distance over the same time interval without changing its direction.Full Answer >
The work of Sir Isaac Newton revolutionized science and laid the foundations of modern mathematics and physics. Among his accomplishments are the formulation of the laws of motion and gravitation, the development of calculus and the invention of the first reflecting telescope.Full Answer >
