QuestionAnswer
In order to calculate pressure exerted on a surface, what quantity is divided by the surface area? Force
If the air inside a balloon exerts a force of 1 N on an area of 0.5 m^2, what is the pressure inside the balloon? 2N/m^2
A pressure of 10 N/m^2 equals 10Pa
Where is fluid pressure greatest? 2 meters below the surface of a swimming pool
Which of the following in NOT a liquid? Air, Gasoline, Cork, Water Cork
The pressure of a fluid at a specific depth... Depends only on the type of fluid
What is the pressure of air at sea level? 101kPa
Which principle states that a change in pressure at any point in a fluid in a closed container is transmitted equally and unchanged in all directions throughout the fluid? Pascals principle
The operation of a hydraulic lift is explained by which principle? Pascals
The hydraulic system of a dump truck is designed to multiply Force
Which principle states that as the speed of a fluid increases, the pressure within the fluid decreases? Bernoulli's Principle
What is the upward force acting on the wing of an airplane in flight called? Lift
What is the upward force acting on an object submerged in a fluid called? Buoyant force
A brick weighs 21N. measured underwater, it weighs 12N. What is the size of the buoyant force exerted by the water on the brick? 9N
The strength of the buoyant force acting on an object in a fluid depends on the objects... Volume
The buoyant force on an object in a fluid is equal to the weight of the... Fluid displaced by the object.
A ball is floating partially submerged in a liquid. The buoyant force acting on the balls equals the... Weight of the ball.
A substance that flows and assumes the shape of its container is a _____ Fluid
As a liquid is added to a beaker, the pressure exerted by the liquid on the bottom of the beaker _________ Increases
The pressure exerted by a fluid at any given depth is exerted _______ in all directions. Equally
A hydraulic jack is an example of _______ principle. Pascals
As the speed of a fluid increases, the _________ within the fluid decreases. Pressure
The downward force produced when air flows over the wing-like spoiler on a race car is an example of ____________ principle Bernoulli's
The direction of the buoyant force on an object placed in a fluid is ______ Upward
Even a rock at the bottom of a lake has a ___________ force acting upward on it. Buoyant
The unit g/cm^3 is often used to express _______ Density
A submerged submarine alters its ________ to rise or fall in the water. Density
For a fluid that is not moving, what are the two factors that determine the pressure that the fluid exerts? Depth and the type of fluid.
Why aren't organisms that live on the seafloor crushed by water pressure? Most organisms on the seafloor are mostly water and they have a high internal pressure.
Why does a partially inflated weather balloon expand as it rises? air pressure decreases with altitude.
On what principle are hydraulic systems based? Pascals principle.
A ball of clay sinks when placed in water. The same piece of clay floats if it is made into the shape of a boat. Compare the volume of the water displaced by the ball with the volume displaced by the boat shape. The boat displaces a greater volume of water than the ball.
Compare the size and direction of the lift on a plane with its weight as it flies at a constant speed and altitude. The lift and weight would have to be the same in order to keep a constant speed and altitude.
When you weight yourself on a bathroom scale, what buoyant force affects the weight reading? buoyant force of the atmosphere.
If you use a spring scaled to measure the weight of a submerged object that has neutral buoyancy, what will the scale read? Zero Newtons
Compare the weight of an object to the buoyant force acting on it if the object sinks in the fluid. If the object sinks then the buoyant force would be less than the weight
