What is Physics?

The branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.

What is Matter?

Physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.

What is Energy?

Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential ...

What is Mechanics?

The branch of applied mathematics dealing with motion and forces producing motion

What is Heat?

The quality of being hot; high temperature

What is Light?

The natural agent that stimulates sight and makes things visible.

What is Sound?

Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.

What is Electricity?

A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.

Basic Physics Concept

Physics is a systematic study of the natural world, a discipline that attempts to quantify reality through a precise application of observation coupled with logic and reason. In order to make use of such a discipline, of course, there is certain foundational information that you must have first, in order to build upon it.

Introduction to Physics

To begin the study of physics, you must first understand what the phrase itself means. Understanding what falls within the realm of physics - and what does not - helps focus the field of study so that you can formulate meaningful physics questions.
