A strong wind blows over the house shown in the figure. The wind is much stronger over the house's roof than lower down, and the house has an open chimney. a window on the ground floor is open, and so are the doors inside the house. Air flow in the window and out the chimney .
Bernoulli's principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed.
Since , the wind is much stronger over the house's roof than down , that means there will be less pressure over the house's roof than down the house . Since , gas travel from high pressure to low pressure . Hence , air flow in the window and out the chimney .

Magma<span> is made up of molten rock, and it is stored in Earth's crust. </span><span> When the volcano erupts, magma flows out of the volcano, it is usually mixed with steam and gas, which is called lava.</span>
In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
