We thus conclude that zero vertical gradient of gravity should be observable by common means, also on the Earth's surface, and not only underground within very dense rocks as some ores can be. Once this is veri

2. Gravity: It's what keeps us grounded on Earth and makes things fall when we drop them. 重力:它让我们在地球上稳稳地立足,也使物体在我们扔下时掉下来。 3. Magnetism: Certain objects, like magnets, have the power to attract or repel other objects. ...
Gravity is a force that pulls objects toward each other.It’s why things fall to the ground when you drop them. On Earth, gravity pulls everything toward the planet’s center, so we stay on the ground instead of floating into space!
