Forces in Fluids

What is Bernoulli's Principle?

• The faster a fluid moves, the less pressure it exerts.

• The more a fluid moves, the less it moves.

• The faster a fluid is, the more we can call it the Flash.

• An object at rest tends to stay at rest.

The buoyant force acts in the direction _______ to the force of gravity, so it makes an object feel light

In a fluid that is not moving (stationary), pressure is exerted equally in all directions.

• False

• True

The faster a fluid moves, the more pressure the fluid exerts.

• False

• True

What causes air pressure

• farts

• the weight of the air around us

• my lies

• air hoses

Air pressure increases as elevation increases.

• True

• False

Water pressure decreases as depth increases.

• True

• False

force/area=

• pressure

• volume

• length

If you know the weight of an object that floats, you know the

• object's density.

• object's mass.

• object's volume.

• buoyant force.

When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This is also known as which principle?

• Pascal's principle

• Newton's principle

• Fitzgibbons' principle

• Bernoulli's principle
