Forces and Fluids

Fluids are substances that can flow and take the shape of their container. This includes both liquids and gases.

The amount of pressure acting on an object is affected by force and surface area.

An object must be more dense than water to sink.

Brenoulli's principle explains how airplane wings create lift.

A liquid can flow and take the shape of its container, but its volume remains constant.

Pascal's principle states that when pressure is applied to a confined fluid, the pressure change occurs throughout the fluid.

Archimedes' principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Pressure is calculated using the formula: Pressure = Force / Area.

Liquids have a definite volume but take the shape of their container, while gases have neither a definite shape nor a definite volume.
