Question

fill in write the techterm that best completes each statement.

1. when you walk across the floor, there is______between your shoes and the floor.
2. as water flows through pipes, the pressure on the pipes from the water is decreased. this is an example of______.
3. when skydivers jump from an airplane, they will reach a______before landing.
4. objects fall to the ground because of the force of______.
5. the pressure in a container of water is measured with a______.
6. the earths force of______pulls objects in the direction of the earths center.

Explanation:

1. When walking, friction opposes relative motion between shoes and floor.
2. Bernoulli's principle states pressure decreases with fluid speed (like water in pipes).
3. Skydivers reach terminal velocity (constant speed) when drag equals weight.
4. Gravity is the force pulling objects to Earth.
5. A manometer measures fluid pressure (e.g., in water container).
6. Earth's gravitational force pulls objects toward its center.

Answer:

1. friction
2. Bernoulli's principle
3. terminal velocity
4. gravity
5. manometer
6. gravity
