Course Description - An Introduction to Physics
Welcome to the world of Physics! Here, we will explore the natural laws of how the universe operates. This introductory course covers all the fundamentals of Physics, and is comprehensive enough for students already familiar with the subject. Join now, and together we'll learn about momentum and energy, force and motion, gravity, particles, the five states of matter, temperature and heat, sound waves, electricity, magnetism, and light.

Course Lessons
Lesson 1: Introduction to Physics
The modern advanced and complex our society becomes, the greater our need for a variety of different types of energy sources. In simpler times, energy was something derived from rubbing two sticks together to create fire.
Lesson 2: Mechanics of Measurement
Despite the vast array of specializations that presently exist, covering everything from acoustics to thermal dynamics, physicists--regardless of their area of expertise--utilize a core continuum of practices.
Lesson 3: Momentum and Energy
Momentum can be defined as 'mass in motion'. This is equally true, for all objects have mass- hence, if an object is in motion then it has momentum-and if it is momentum, by and large, it is 'mass in motion.'
Lesson 4: Force and Motion (Newton's Laws of Motion)
Back in the late 1600s, Sir Isaac Newton, one of the most notable scientists and mathematicians in history published his now legendary 'Laws of Motion' within his book entitled, Philosophiae Naturalis Principia Mathematica. Since, the laws formed the basi
Lesson 5: Gravity
Whatever goes up-must come down. This famous statement refers to the basic tenets of gravity, hence, an explanation as to why objects fall to Earth.
Lesson 6: Systems of Many Particles
With respect to objects of noticeable size, we work with them by envisioning that they are made up of numerous smaller pieces-these then are referred to as 'particles.'
Lesson 7: Solids
While you have probably studied or learned about solids as they relate to chemistry; when applied to physics, the subject of solids focuses more on the bulk matter as opposed to the individual particles that comprise it.
Lesson 8: Gases and Liquids
Within the previous chapter, we touched upon the three (well, primarily there are three) states in which a substance can be found: solid, liquid and gas.
Lesson 9: Temperature and Heat
Temperature is a central component within physics. In short, within physics, the transfer of energy, internally, from one part of substance to another, or, externally, from one body to another occurs on account of differences in temperature.
Lesson 10: Energy, Work, and Heat (Thermodynamics at work)
We cited the differences between heat and temperature, listed and described the range of measurement scales available to track temperature, and identified the different states (phases) substances which may be found based upon temperature factors and press
Lesson 11: Wave Motion
Waves can be found anywhere and everywhere. Consider for a moment several commonly found examples: sound waves (discussed in greater detail in the subsequent chapter), light waves, radio waves (frequency), telecommunication waves, and microwaves (seriousl
Lesson 12: Sound Waves
Fundamentally speaking, sound is a mechanical wave. Our ears have then been constructed as conduits as such waves--meaning they serve as receivers for the mechanical waves transmitted through the air from a specified point of origin.
Lesson 13: Static Electricity
Defined as the state in which electrical charges build up on the surface of a material, 'Static Electricity' received its name on account of the lack of a flowing current.
Lesson 14: Electrical Induction
Prior to even beginning to broach the subject of electrical induction, we first will need to define the individual components which comprise the state referred to as 'electrical induction.'
Lesson 15: Electrical Current
The scientific definition of 'electrical current' includes the concept of speed-meaning the rate at which the charge is moving (flow) through the channel.
Lesson 16: Electromagnetic Waves
Both electricity, e.g., your hair sticking straight up and magnetism can be static, e.g. a refrigerator magnet. However, when the two change or come together, they form a specific type of wave known as electromagnetic waves.
Lesson 17: Magnetic Effects of Current
Not only do electric currents flow through the universe but magnetic currents do, as well.
Lesson 18: Quantum Nature of Light
Whereas physics attempts to describe the rules as they apply to movement and matter; quantum physics tries to explain the behavior of even smaller particles in combination with movement. Such particles include things the likes of: electrons, protons, and
Lesson 19: Light as a Wave
While we touched on the nature of light, the varying types which exist along the electromagnetic spectrum and, even delved a bit into, the idea of light as a wave formation, we kept the crux of our discussion on the first two rather than heavily focusing

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself.
"All the lessons were written such that I, lacking any prior physics knowledge, had no difficulty understanding the subject matter discussed....I very much enjoyed the class, some parts of physics are no longer a secret to me!" -- Cindy H.
"I was completely in the dark about physics and was a little nervous about tackleing this subject. Now I have a lot better understanding.
...The instructor was very prompt on grading my exams and getting the results back to me. I am very glad that I took this course." -- Rodney C.
"I am generally well-pleased with the course." -- Michael D.
