Fluids and Forces

What is an upward force applied by a fluid on an object in the fluid.

• Pressure

• Drag Force

• Buoyancy

• Pascal's Principle

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

• Archimedes' Principle

• Bernoulli's Principle

• Atmospheric Pressure

• Pascal's Principle

What is Pressure?

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

• The amount of force per unit area applied to an object’s surface.

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

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

What is drag force?

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

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

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

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

Density formula

• Density= mass*volume

• Density=volume/mass

• Density= mass + volume

• Density= mass/volume

What force counteracts buoyancy?

• Water Pressure

• Gravity

• Air Pressure

• Drag Force
