Basic Physics Terms


Introduction to basic physics terms

The word Physics is a Greek word which meant the natural science. The word nature was introduced by ancient scientist Aristotle in year 350 B.C. The Sanskrit word for the physics is Bhauitaka which refers to the physical world. Physics involves the study of matter and its motion in the space. Physics is the branch of science in which we deals with the study of basic laws of nature and their many natural phenomenons. It is concerned with the interaction of matter with matter or energy. It deals with the various features of natural world such as space, time, motion, energy, radiation, etc. Physics is one of the oldest branches of science.

Basic Branches of the Physics Terms

Physics has two main domains of study one is macroscopic and the other is microscopic. Classical physics deals with macroscopic phenomena which may be at the laboratory, terrestrial and astronomical scales. It includes the branches like mechanics, optics, thermodynamics and electrodynamics. Quantum physics deals with microscopic phenomena at the minute scale of atoms, molecules and nuclei.

Classical physics deals with macroscopic phenomena which may be at the laboratory, terrestrial and astronomical scales.

The basic terms of the physics are as follows:

Motion: The body said is in motion if its position changes with respect to time.

Rest: A body said to be in rest if its position does not changes with respect to time.

Point object: If the position of the object changes by the distances much greater than its own size in a reasonable duration of time, then the object may be regarded as the point object.

Scalar Quantities: The physical quantities which can only be calculated by their magnitudes are called the scalar quantities, such as time, distance etc.

Vector Quantities: The physical quantities which can completely be described by their magnitude and the direction are called the vector quantities, such as displacement, velocity, force etc.

Distance: It is the length of the actual path traversed by the body between its initial and the final positions.

Displacement: It is defined as the change in the position of the object in a fixed direction. It is given by the vector drawn from initial position to the final position of the object.
