Part E

Based on your observations in parts A through D, explain why Earth's gravity pulls vou toward the ground

The gravitational pull between two objects increases as the distance between them decreases. The gravitational pull also increases with an increase in the mass of the objects. Earth has a large mass. So, when our bodies are close to Earth, the gravitational pull between us and the Earth is strong. This force pulls us down, so we stand firmly on the ground without floating in the air. Without the gravitational force, we would drift away from Earth.

On Plato.

Gravity causes the Earth to constantly pull us down. That's why we always have our feet on the ground. But it is not necessary to be in direct contact with the Earth to attract us. It is enough that we are not very far from it. This is the reason why our planet revolves around the Sun and the Moon does it around the Earth.
