I guess gravity is stronger than centrifugal force.

in english, its simply gravity. the definition of gravity in physics is the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface. Take this for example. Take a World War 2 fighter plane, the P51 Mustang. When a pilot pulls back on the stick, the plane will go up higher. But because of gravity, the plane will slowly lose speed and eventually stop going up and start falling down. Hint the expression "what goes up, must come down".
Gravity is what keeps your feet and the ground and from floating into the sky. Its why the birds and the bees have wings. There it is in a nut shell. Hope it helps.

That depends on which way the water spills into the bathtub, and how the bathtub is built. Contrary to popular opinion, it doesn't depend on the bathtub's latitude.
The inertial force with which the rotating Earth affects air and water masses is known as the Coriolis effect or Coriolis force. It's the reason why cyclones rotate clockwise in the southern hemisphere, and counterclockwise in the northern. However, you need huge amounts of moving air and water for it to take effect. In the case of a bathtub, the water drain is primarily affected by the shape of the drain and residual currents in the plumbing.

Water flows "down potential", not "down". Any fluid will move to its point of lowest potential energy. If water is flowing down a hill, it may increase in velocity enough to go uphill at some point further down stream.
For example, water under pressure in an underground aquifer is sometimes called an artesian spring where it pierces the surface; geysers (which are hot water under pressure), can spary up into the air several yards. Hot springs bubble up. Cold water sinks. It's all a matter of energy!

Because gravity force. Any body or sustance heavy enough will be always atttracted down to the center of Earth by the gravity force.
