🛰️ How do satellites stay in space?

Satellites stay in space because they are moving super fast! 🚀 Just like when you swing a ball on a string, it goes around and around. Satellites zoom around the Earth so quickly that they don't fall down. 🌍✨

They are like little space cars driving in circles around our planet!

Satellites stay in space because of two things: speed and gravity! 🌎🚀

When a satellite is launched, it’s given enough speed to orbit Earth. Earth's gravity pulls it down, but the satellite's speed keeps it moving forward. This balance makes it go in a circle around Earth—like a never-ending fall!

This is called an orbit. Different satellites orbit at different heights and speeds.

Satellites stay in space due to a perfect balance between velocity and Earth's gravitational pull. 🛰️🌍

When a satellite is launched, it reaches a speed called orbital velocity (about 17,500 mph for low Earth orbit). At this speed, the satellite's forward motion matches Earth's curvature, causing it to continuously "fall" around the planet instead of crashing back down.

Key concepts:

• Centripetal force: Gravity acts as the force pulling the satellite inward.
• Inertia: The satellite's speed keeps it moving forward.

Higher orbits (like geostationary satellites) move slower because gravity weakens with distance.
