Forces and Fluids

Front

What two factors affect the amount of pressure acting on an object?

Back

Force and surface area.

Front

What force acts upward on an object submerged in a fluid?

Back

Buoyant force.

Front

In a hydraulic system, what remains constant?

Back

Input work equals output work.

Front

What principle states that the pressure of a fluid decreases when the speed of that fluid increases?

Back

Bernoulli's principle.

Front

True or False: An object sinks because its weight is greater than the buoyant force.

Back

True.

Front

What is pressure?

Back

Pressure is the force applied per unit area.

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid on an object immersed in it.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.

Front

What does Pascal's principle state?

Back

A change in pressure applied to an enclosed fluid is transmitted undiminished to all parts of the fluid.

Front

What is Archimedes' principle?

Back

An object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.
