I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it started moving? You might think it's all about weight, but actually it's about friction. Two kinds of friction! In today's episode of Crash Course Physics, Shini Somara tells us about Static and Kinetic friction; how they work and how they're different.

Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawn mowers.

CALCULUS! Today we take our first steps into the language of Physics; mathematics. Every branch of science has its own way to describe the things that it investigates. And, with Physics, that's math. In this episode, Shini talks us through derivatives and how calculus helps us to understand the world around us.

When you hear the word, "Work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to walk us through it. Also, Energy and Power!

Вы уже знаете, что все тела на поверхности Земли испытывают ее притяжение. На любое тело, находящееся на поверхности Земли или вблизи ее, сила тяжести. Снежинка, падающая с неба, движется к Земле. Но, упав на крышу, она прекращает свое движение. Значит, что-то мешает снежинке двигаться вниз.

RussianHi! 👋 I'm Andrey Shcherbakov, an economics teacher who enjoys making complex ideas simple and practical. For me, economics isn't just a school subject—it's a way to understand how the world works. 🌍 From personal finance 💰 and entrepreneurship 🚀 to inflation 📈, investments 📊, and global markets, economics helps explain the decisions we make every day. My teaching style is interactive, structured, and focused on real understanding rather than memorization. I explain difficult concepts step by step, using current events, business examples, visual materials, and real economic situations that make learning both interesting and useful. I work with students preparing for exams 🎓, university courses, Olympiads 🏆, or anyone who wants to improve their financial literacy and analytical thinking. Every lesson is personalized to match your goals, learning pace, and experience. I believe that confidence comes from understanding. 💡 That's why my lessons encourage questions, discussions, and practical problem-solving instead of simply learning definitions. If you're looking for clear explanations, engaging lessons, and real progress 📚, I'd be happy to help you discover that economics can be both fascinating and useful. I look forward to meeting you! 😊
