Introduction to physics This introduction to physics is for anyone with a desire to learn physics. You are a student in high school and you need a solid introduction to help you tackle the jargon you hear from your teacher. You are in college and you feel like you are falling behind. Get back on tract here before it is too late You are just curious about physics. You have never learned physics before and you need some good guidelines to get started without the exorbitant cost of taking a course. Just like mathematics, it is hard to separate physics from the world we are living in A little history Everything started with the study of natural philosophy. Natural philosophy used to be the study of unanswered questions about nature. As more and more answers are found, natural philosophy became science. The physical sciences deal with nonliving things and branch into areas such as physics, geology, astronomy, and chemistry. Introduction to physics or rocket science course? Goals We will of course study physics here and introduce the most important topics to include Mechanics : linear motion, Newton's laws, circular motion, etc. Properties of matter : liquid , solid, or gas Electricity and magnetism : electric current, circuits, tec. What you get on my site is an introduction. You will not be ready to put together a rocket. However, I will help you understand all the subtleties that will prepare you for more challenging courses in physics. No serious study can be done without a good understanding of mathematics. We will not try to cloud physics with math, but math will help understand physics. Keep in mind that the better you understand math, the more comfortable you could be with physics. The better you understand physics, the more well rounded you could be with other branches of sciences. The scientific method 1. Identify a problem 2. Make an educated guess about the answer. This is called hypothesis. 3. Perform experiments to test your hypothesis 4. Formulate a general rule When the last step in the scientific method is tested over and over again and it is still not contracted, it is then known as a law or principle. Sometimes, scientists find new evidence that contradicts a law or principle. In this case, the previously accepted lay or principle must be rejected until another one is found. The introduction to physics you get in this site will explain laws and principles that are accepted as of today. Physics is a progressive science as scientists change their mind all the time, so don't be shock when a change is made. it is a good thing when they change their minds and find a better solution to explain our physical world. Units of Speed Learn what the units of speed are. Learn also how to convert a unit to another such as miles per hour to kilometer per hour Adding Vectors adding vectors using arrows is what you will learn here Trigonometric Identities A list of the basic trigonometric identities with some good illustrations. Definition of Speed A definition of speed is given with crystal clear explanations and examples Definition of Velocity A definition of velocity is given with crystal clear explanations and examples. Velocity versus speed is also explained. Definition of Acceleration A definition of acceleration is given with crystal clear explanations and examples. The difference between speed and acceleration is also explained. Free Fall Equations Find here the free fall equations and an explanations of where these equations came from Graph of Speed Learn to read the graph of speed versus time Definition of Inertia A definition of inertia along with great discoveries by famous mathematicians and physicians such as Galileo and Newton Newton's Second Law Newton's second law of motion is explained here in plain English. Learn how to derive the formula F = m x a Third Law of Newton Explanations and examples of the third law of newton. Learn about action and reaction Difference between Rotation and Revolution Learn quickly the difference between rotation and revolution How to Calculate Momentum This lesson will show you how to calculate the momentum of moving objects Work Formula Find the work formula here and learn about the meaning of work in physics Vibrations and Waves Understand quickly the meaning of vibrations and waves with crystal clear explanations What is a Neutral Atom What is a neutral atom? Find out what an atom is with crystal clear explanations What is Temperature? What is temperature?
