Here's why:
* Gravity: The Earth's gravity pulls on the projectile, constantly trying to bring it down.
* Horizontal Velocity: The projectile also has a horizontal velocity, which keeps it moving forward.
* Balance: If the horizontal velocity is high enough, the projectile will continuously fall towards the Earth, but its forward motion will cause it to miss the Earth's surface, and it will continue orbiting.
Key Points:
* Orbit: A satellite is in orbit when it's constantly falling towards the Earth, but moving forward fast enough that it misses the surface.
* Types of Satellites: There are many types of satellites, including communication satellites, weather satellites, and scientific research satellites.
