Forces and Pressure

The ratio of the weight of all the air above you to your surface area

• fluid

• atmosphere

• atmospheric pressure

• buoyant force

Any substance that can flow and take the shape of the container that holds it

• gas

• liquid

• fluid

• solid

The amount of force per unit area applied to an object's surface

• pressure

• force

• work

• mass

An upward force applied by a fluid on an object in the fluid

• Bernoulli

• Buoyant force

• gravity

• Archimedes

The weight of the fluid that an object displaces is equal to the buoyant force acting on the object

• Archimedes' Principle

• Bernoulli's Principle

• Pascal's Principle

If the weight of an object is greater than the buoyant force what happens?

• It sinks

• It floats

• It goes up in the air

If the weight of an object is equal to its buoyant force what happens?

• it sinks

• it floats

• it goes up in the air

Pressure=

• force/area

• area/force

• weight/force

• weight/area

The pressure of a fluid decreases when the speed of that fluid increases.

• Archimedes' Principle

• Bernoulli's Priciple

• Pascal's Principle

A force that opposes the motion of an object through a fluid.

• pressure

• buoyant force

• drag force

• fulcrum
