The apple would continue orbiting Earth alongside the spaceship.
Here's why:
* Orbital Mechanics: Objects in orbit are constantly falling towards Earth due to gravity, but they also have a sideways velocity that keeps them from hitting the ground. This balance of falling and moving sideways creates a circular or elliptical orbit.
* Shared Velocity: The apple inside the spaceship is traveling at the same speed and in the same direction as the spaceship. When released, it inherits this velocity.
* No Air Resistance: In the vacuum of space, there's no air resistance to slow the apple down.
What would happen if you threw the apple?
* Slight Changes: If you threw the apple with a little force, you could slightly change its orbit. A throw forward would make the orbit slightly larger, while a throw backward would make it slightly smaller.
* Significant Changes: A very strong throw could potentially change the orbit enough to cause the apple to eventually re-enter the Earth's atmosphere and burn up.
Important Note: This assumes the spaceship is in a stable orbit around Earth. If the spaceship was on a trajectory to another planet, the apple would follow the same path.
