Floating or Sinking?
Increase or Decrease?
Which has greater pressure?
Which Principle?

### 100

The force exerted on a surface divided by the total area over which the force is exerted.
What is pressure?

### 100

The force that pulls objects toward each other.
What is gravity?

### 100

Pressure does this as the area over which a force is distributed increases.
What is decreases?

### 100

A skydiver or a boat on the ocean?
What is Boat?

### 100

This principle states that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces.
What is Archimedes' Principle?

### 200

The ratio of the mass of a substance to its volume.
What is density?

### 200

A measure of the force of gravity on an object.
What is weight?

### 200

As your elevation increases, atmospheric pressure does this.
What is decreases?

### 200

A skydiver at 3,000 m or a mountain climber at 8,000 m?
What is the skydiver?

### 200

When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.
What is Pascal's Principle?

An upward force.
What is lift?

### 300

The upward force exerted by a fluid on a submerged object.
What is buoyant force?

### 300

Water pressure increases as depth does this.
What is increases?

### 300

The pilot at a commercial airplane or a scuba diver?
What is the scuba diver?

### 300

This principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases.
What is Bernoulli's Principle?

### 400

A substance that can easily flow.
What is fluid?

### 400

Changes in this cause a submarine to dive or rise.
What is density?

### 400

Bernoulli's principle states that as the speed of a moving fluid increases, the pressure within the fluid does this?
What is decreases?

### 400

An aircraft carrier or a submerged submarine.
What is the submarine?

### 400

The principle that explains what an auto mechanic uses and works with every day.
What is Pascal's Principle?

### 500

An instrument used to measure atmospheric pressure.
What is a barometer?

### 500

The buoyant force acts in the direction opposite to the force of gravity, so it makes an object feel this.
What is lighter?

### 500

In a hydraulic device, a force applied to one piston does this to the fluid pressure equally throughout the fluid.
What is increases?

### 500

A scuba diver at 15 m deep or a scuba diver at 50 m deep?
What is the scuba diver at 50 m deep?

### 500

The principle that is used every day by airplanes and helicopters.
What is Bernoulli's Principle?
