Depends on how steep the hill is.
so water can go down hills so the water doesnt stay in the same place
Safa and Marwa are two hills in the middle of the desert. Muslim Pilgrims go there whilst they are on hajj. It is believed that Hagar walked up and down these two hills seven times to look for water. Muslims follow her footsteps but instead of walking up and down the hills they go down this long corridor going from one hill to the other to protect them from the heat.
it dosent go down as fast as temperature water would

As fast as the water is moving.
Yes. Tornadoes can go up and down hills largely unhindered.
Go down the hill.
Calm it down, give it a drink of water, and it my slow from relaxation. If that doesn't work, i would go to a vet
an inclined boared or long board
No. But it does go pretty fast and high.
Boatercycles (Jetskis) can be fast, depending on how immensely fat the person is, and depending on how much water there is and how fast the engine is designed to go
Up hill. It builds energy, and strenth. Going down hill doesnt do much
