100
This is a material that can flow and that takes the shape of its container.
What is a Fluid?
100
This SI unit for force is called this. One of these is equal to a force of one newton pushing on an area of one square meter.
What is a Pascal?
100
This is the upward force that a fluid exerts on all objects in the fluid.
What is buoyant force?
100
When the buoyant force of an object is greater that the objects weight, the object is known to be this.
What is buoyed up?
100
This is a force in a fluid that opposes or restricts motion.
What is drag?
200
This is the force exerted on a given area.
What is Pressure?
200
As altitude increases, this happens to atmospheric pressure.
What is decrease?
200
This produces buoyant force.
What is pressure from a displaced fluid?
200
This states that as the speed of a moving fluid increases, the fluid's pressure decreases.
What is Bernoulli's Principle?
200
This is the irregular or predictable flow of fluids.
What is turbulence?
300
This is the reason why bubbles are round.
What is the gas inside the bubbles exert the same pressure in all directions.
300
Atmospheric pressure is greatest here.
What is on the earth's surface?
300
A Greek mathematician stated that the weight of displaced water equals the buoyant force of the water. This is known as this.
What is Archimedes' principle?
300
Several factors influence flight. This factor is the upward force exerted on a plane's wings.
What is Lift?
300
If a pitcher wants a pitch to travel away from a right handed batter, the ball should have this rotation.
What is counterclockwise?
400
This is the formula for calculating pressure.
What is pressure = force/area?
400
This is a measure of how closely packed the particles in a substance are.
What is Density?
400
An object in a fluid will do this if its weight is greater than the buoyant force.
What is sink?
400
This factor that influences flight is the forward force that the plane's engines produces.
What is thrust?
400
This states that a fluid contained in a vessel exerts pressure of equal size in all directions.
What is Pascal's Principle?
500
The weight of the atmosphere is called this.
What is Atmospheric Pressure?
500
Air tends to go from areas of this type of pressure to this type of pressure. (two answers)
What is high, low?
500
An object does this when the buoyant force and its weight are equal.
What is float (or suspended)?
500
When a bird flaps its wings, it supplies these. (2)
What is thrust and lift?
500
These types of devices use Pascal's principle to move or lift objects.
What are hydraulics?
