Doodling about reference frames 🌍
-
What's a reference frame? Think of it like a big, invisible grid that helps us talk about where things are in space! It's like using a map to point out where you live.
-
Main Components
- A starting point or origin.
- A set of axes. Imagine drawing lines on your map to make it look like a grid.
-
Popular Frame: The Cartesian Reference Frame 📏
- Most loved in IBDP Physics.
- Ever seen a 3D graph? That's our guy.
- Positions are like game coordinates: (x, y, z).
- Imagine standing in a giant box: you have length (x), width (y), and height (z)!
-
But there are others 🌐
- Ever heard sailors talk about latitude and longitude? They’re using angles to locate themselves on the Earth. Add in how high you're flying in the sky (distance from Earth's center), and you've got another way to describe positions, without needing x, y, and z!
-
Stargazing tip 🌌: Astronomers use angles to spot stars. They just need two angles. Why? Because they usually don’t worry about how far away the star is.
The spinning earth & crazy frames 🎡
-
Our planet is like a merry-go-round. If you stand on it (like we all do), it feels like everything in space is spinning around us. It's like being at the center of a gigantic universal disco party!
-
Plot Twist: Anything that seems still to us on Earth isn't really cruising straight and steady. That's why
- We came up with a make-believe force: “centrifugal” force. Like when you spin super fast on a merry-go-round and feel like you're about to fly off.
- There's also the Coriolis force, another pretend force. It's like the unseen hand guiding hurricanes on their curvy paths.
