### 5 Matching questions

1. What is air pressure?
2. What are some example's of hydraulic lifts?
3. As depth in water increases, pressure
4. What does Archimedes' principle state?
5. What is the formula for density?
1. a that the buoyant force that is acting on an object is equal to the weight of the water that is displaced
2. b mass/volume
3. c fire truck, machines that raise cars
4. d the earth's atmosphere is constantly applying pressure (example)
5. e increases

### 5 Multiple choice questions

1. decreases
2. force/area
3. with a barometer
4. The faster the fluid moves, the less pressure it exerts within the fluid.
5. The amount of force exerted on a surface

### 5 True/False questions

1. When will an object float?the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.

2. How do chimneys take advantage of Bernoulli's principle?the wind on top of the chimney creates a lower pressure at the top, on the bottom is a greater pressure which forces the smoke and heat to rise

3. What does Pascal's Principle state?when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.

4. How does a submarine dive?By increasing its density with water and overcoming the buoyant force by adding more weight and not changing the volume and therefore not displacing anymore water to increase the buoyant force.

5. What are some examples of Bernoulli's principle?chimneys, planes (flying disks), and atomizers
