Classical Mechanics (Goldstein book)
Okay, so imagine you're playing with a toy car. You push the car forward and it rolls, right? Well, classical mechanics is the big-kid way of figuring out how that toy car moves and why.
There are three important things to remember when it comes to classical mechanics: motion, force, and energy.
When you move something, that's motion. When you push your toy car, that's motion. But there are different types of motion! Sometimes things move in a really straight line, sometimes they go in circles, sometimes they zig-zag. Classical mechanics helps you figure out how things move in different ways.
Now, force. When you push the toy car, you're using force to make it move. But did you know there are lots of different types of force too? There's friction, gravity, and even the air around us can be a force. Classical mechanics helps you figure out how different types of force affect how things move.
Lastly, energy. This one is a little more complicated, but it's basically like a battery that powers the toy car. When you push the car, you give it energy. But sometimes that energy can run out, or sometimes you can get more energy by using a different type of force. Classical mechanics helps you figure out how energy is used and how it changes as things move.
Goldstein's book is like a big, grown-up book that helps people learn even more about motion, force, and energy. It teaches you things like how to use equations to predict how something will move, or how to take into account lots of different types of force. It's really useful for scientists who want to understand how things move in the real world, and how to create machines that move in ways we want them to.
