Introduction to physics

Khan AcademyPhysics Basics

Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. So chemistry, chemistry is actually laid down on a foundation of physics. And what we'll see, even classical mechanics, the physics that Newton established, can explain a large range of phenomena with amazing precision. Torque and angular momentum.

And physics really does try to use that mathematics along with some core ideas to explain the phenomena, all the phenomena, of the universe. And then even when we think about ourselves, our bodies, even our consciousness, our brains, it really all boils down to chemistry and physics. Centripetal force and gravitation.

And so as you go into your study of physics, I wanna leave you with some quotes from these three gentlemen. Electromagnetic waves and interference. At its essence, it's all about trying to explain the complexity of the universe, predict what is going to happen based on simple ideas. Displacement from time and velocity example Displacement, velocity, and time.

Forces and Newton's laws of motion. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry. But physics is the foundation for all of the other sciences. Magnetic forces, magnetic fields, and Faraday's law.

Introduction to work and energy Work and energy. Simple or elegant mathematics like force is equal to mass times acceleration. What is the nature of reality? How does the universe actually work?

Now a lot of times, we think physics is only limited to things like cosmological phenomena or getting rockets into space, or how waves move or building structures. Some of the things that I just mentioned, these ideas, we're gonna explore ideas of energy. In fact, I'm sure we don't know who the first physicists were.

Learn the essentials of understanding physics through these instructional videos for students at all levels. We'll go into much more depth in future videos.

And even a great thinker like Isaac Newton, he recognized this. In the field of physics, which you could view maybe right after mathematics as the purest of the sciences.

In some ways, it's an illusion that our mind creates so that we can operate inside of it. And physicists will the the first to admit that they are just beginning to understand the nature of reality, the nature of everything around us. Intro to vectors and scalars. And then, you are getting closer to the truth.

Amazing Videos for Teaching and Studying Physics

See what you should do to prepare for your upcoming physics class. Triboelectric effect and charge Charge and electric force Coulomb's law. Physics is the study of the basic principles that govern the physical world around us. But some of the, I guess you could say foundational thinkers in physics are these gentlemen that I have here.

Preparing to study physics. When we think about chemistry, when we think about chemistry, which is at the end of the day interactions between atoms, majaa tamil movie those interactions are really physics-based interactions.

Impacts and linear momentum. Electromagnetic waves and the electromagnetic spectrum Introduction to electromagnetic waves. Intro to vectors and scalars Displacement, velocity, and time. And we're gonna talk about force and acceleration as vector quantities.

As you study physics, you will start to see, whoa, most of what we consider to be reality, our current understanding is based on these forces, but what are these forces? So as you go into your study of physics, and I'm kind of a physicist wannabe. First and foremost, we'd wanna include Isaac Newton. Newton's first law of motion introduction Newton's laws of motion.

We'll learn things like accelaration is equal to change in velocity over change in time. If you're seeing this message, it means we're having trouble loading external resources on our website. Now, I love this second quote from Isaac Newton.

Few things make an abstract concept clearer than seeing how it works in real life. So you have math, which is very pure, and then on that foundation of math you have physics. Loop de loop question Circular motion and centripetal acceleration. These lectures and videos focus on explaining or elaborating on more specific concepts in physics, both at a basic and more advanced level. And so even biology, even what we are, is built on a foundation of chemistry.

These documentaries address some of the major questions in physics and entertain while they educate. Displacement is equal to velocity times time. Normal force in an elevator Normal force and contact force. Going into some mathematics, proving some formulas. And these are the questions that physics is attempting to answer.

If you're trying to teach students, or if you're the student yourself, these videos can go a long way towards illustrating concepts in a fun, informative way. Lunar eclipse Modeling the solar system. And last but not least, and there's actually a ton of great quotes from these folks and others, but especially Albert Einstein. And you realize these very tangible things aren't so tangible after all.

We're gonna think about things like displacement, and I'll put it as a vector quantity, and we'll soon learn more about vector and scalar quantities are. We'll start by looking at motion itself. We're going to explain, we're gonna think about what are the the different types of forces out there, and why they might, why they might actually exist.

You can explain all sorts of complex phenomena. There will be times where we're going to be building our tool kits. These videos will do just that, making things like light, motion and friction easier to understand.

And that's what physics is all about. That's where the web can come to the rescue.
