Question

Why was the Earth's satellite left behind?​

Answer 1

• Because satellites circle the Earth, they do not fall from the sky.

• Earth's gravity pushes on satellites even when they are hundreds of miles distant.
• Gravity, along with the force of the satellite's launch into space, causes the satellite to fly into orbit above Earth rather than fall back to Earth.

• Satellites are able to orbit the Earth because they are locked into speeds that are fast enough to overcome gravity's downward pull.
• A satellite's orbit is maintained by balancing two factors: its velocity (the speed required to proceed in a straight line) and Earth's gravitational attraction.

Answer 2

Answer:

1. Satellites don't fall from the sky because they are orbiting Earth.

2. Even when satellites are thousands of miles away, Earth's gravity still tugs on them.

3. Gravity--combined with the satellite's momentum from its launch into space--cause the satellite to go into orbit above Earth

4. Instead of falling back down to the ground.
