Question

4) What can we see in the sky because of gravity?

Answer 1

A:we can see birds, drones, airplanes all because of gravity. If you want to get bigger, we can see our Sun and planets revolve because of gravity, orbital mechanics and light.

B:With less gravity, it is harder to keep your body strong. If the Earth's gravity is lost, all items held to the Earth's surface by gravity would float away. That includes the atmosphere, water, people, cars and animals. If an object were secured strongly to the Earth, it would probably remain attached.
