If the Earth is round, why don't we walk upside down?

The force of gravity pulls all objects towards the center of the Earth, so no matter where you are on the planet, you are always being pulled towards the ground. This is why we don't walk upside down even though the Earth is round. Gravity keeps us firmly planted on the ground no matter which way we are facing.

The Earth's gravity pulls us towards its center, which is why we don't walk upside down. Gravity is not a physical force that points downwards, but rather a force that acts towards the center of mass of any object. In the case of the Earth, the center of mass is at its center, so gravity pulls us towards the center of the Earth. This force is what keeps us on the ground and prevents us from floating away into space.

The shape of the Earth does not affect the direction of gravity. Gravity is a force that acts between any two objects with mass, regardless of their shape. The Earth's shape is roughly spherical, but it is not perfectly round. It is slightly flattened at the poles and bulges out at the equator. However, these irregularities do not have a significant effect on the direction of gravity.

The reason why we don't walk upside down is because gravity pulls us towards the center of the Earth. This force is stronger than any other force that might be acting on us, such as the force of the wind or the force of our own muscles. Gravity keeps us grounded and prevents us from floating away into space.
