TEXT I Comprehensive reading SOME FACTS ABOUT PHYSICS Physics deals with matter and energy and how they interact. It begins by examining the information that people sense about the world around them.

Objects are seen to move* from place to place, and when completely free of contact** with other objects, they move in straight lines at a steady speed. Being at rest objects are said to move at a steady zero speed, whenever objects do not behave this way, they are said to be accelerated***, and a force is said to act on them****.

The internal quality of the object is called mass. When forces act on objects the accelerations produce changes in such things as position, size, shape and chemical nature. The kind and size of any change is judged by***** use of a quantity called energy.

Therefore, energy forms include light, heat, sound, magnetism and electricity.

Traditionally physics is divided into several major topics, namely, mechanics heat, optics, electricity and magnetism, atomic physics and nuclear physics. Because of the remarkable unity of Nature this separation into topics is, to some extent, artificial and exists for convenience.

Newtons second law, relating force to acceleration and his third law relating action and reaction, form the basis of mechanics. Maxwells equations which combine in mathematical form the laws discovered by Ampere, Faraday, form the basis of electricity, magnetism and optics.

An understanding of statics is necessary to describe the behavior of bulk matter and, with the laws of mechanics, electricity and magnetism, forms the basis of heat and thermodynamics. All these subdivisions constitute classical physics of the end of the 19th century. Modern physics began with the work of Plank and the theory of relativity.

Atomic physics made it possible for Mendeleyev to construct his Periodic Table of Elements, to predict their properties and to understand the nature of atomic spectra.

Nuclear physics has been rapidly developing since 1930 s. It includes the discovery of the neutron and other fundamental particles; the creation of artificial radioactivity, the discovery of nuclear fission and fusion; the development of particle accelerators for bombarding nuclei with particles possessing billions of electron volts of energy.

Active research flourishes in many other fields such as:

-solid state physics and cryogenics -study of properties of matter at very low temperatures, including superconductivity;

-microwave and radio frequency spectroscopy.

Plasma physics is growing rapidly because of the current search for controlled thermonuclear fusion and because of the exploration of space.
