When a force is applied to a fluid in a closed container, the pressure in the fluid increases everywhere by the same amount.

• weight
• work
• Pascal's principle
• hydraulic system
• Bernoulli's principle

A set of processes that uses a fluid to increase an input force.

• weight
• work
• Pascal's principle
• hydraulic system
• Bernoulli's principle

When the speed of a fluid increases, the pressure exerted by the fluid decreases.

• weight
• work
• Pascal's principle
• hydraulic system
• Bernoulli's principle

The force per unit area that is applied to the surface of an object.

• buoyant force
• pressure
• fluid
• density
• Archimedes' Principle

Any substance that has no definite shape and has the ability to flow.

• buoyant force
• pressure
• fluid
• density
• Archimedes' Principle

An upward force that is exerted by a fluid on any object in the fluid.

• buoyant force
• pressure
• fluid
• density
• Archimedes' Principle

The buoyant force on an object is equal to the weight of the fluid it displaces.

• buoyant force
• pressure
• fluid
• density
• Archimedes' Principle

The mass of an object divided by the volume it occupies.
