Question

what is gravitation? come who show? ​

Answer 1

Earth's gravity is what keeps you on the ground and what makes things fall.

Gravity is measured by the acceleration that it gives to freely falling objects.

At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

Gravity is actually made of quantum particles, which they called "gravitons."

Gravity is strongest at the Earth's surface, and its weakest at the Earth's core.
