Physics, the basic physical science, studies objects ranging from the very small (using quantum mechanics) to the entire universe (using general relativity). It deals with the structure of matter and …

Mechanics, branch of physics concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest. Historically, mechanics was among the first of the …

Physics is one of the major branches of science. People who work in physics are called physicists. Physicists study matter and the forces (pushes or pulls) that act on it.…

The study of quantum mechanics is rewarding for several reasons. First, it illustrates the essential methodology of physics. Second, it has been enormously successful in giving correct results in …

The term is derived from the Greek akoustos, meaning “heard.” Beginning with its origins in the study of mechanical vibrations and the radiation of these vibrations through mechanical waves, acoustics has …

Physics attempts to describe and explain the physical universe. Physicists therefore try to discover one or more laws—invariable principles of nature at work—that will describe a large class of phenomena.

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the …

The branch of physics concerned with atomic and subatomic systems is known as quantum mechanics. Its aim is to account for the properties of molecules and atoms and their even tinier constituents, …
