Internal Structure and Density
This fundamental physical property is defined as the ratio of an object's mass to its volume, often represented by the Greek letter p.
What is density?
This is defined as the force exerted perpendicular to a surface divided by the area over which that force is distributed.
What is Pressure (P =F/A)
According to Newton's First Law and fluid statics, this is the net force acting on an object that is floating at rest on the surface of a liquid.
What is zero
This principle of mass conservation for an incompressible fluid states that the product of the cross-sectional area and the fluid's velocity remains constant throughout a pipe.
What is the Continuity Equation? (A1v1=A2v2)
This type is the only one that is super-effective against itself
What is Dragon
In this model of matter used in AP Physics, the internal structure of a solid is often represented as a lattice of spheres connected by these, which explain why solids resist compression and stretching
What are springs (or interatomic/intermolecular forces)?
According to the formula P =P0+pgh, this type of pressure is caused by the weight of the liquid above a certain point.
What is Gauge Pressure (or Hydrostatic Pressure)?
This principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object
What is Archimedes' Principle?
Often called "Conservation of Energy for Fluids," this equation relates pressure, flow speed, and height at any two points in a steady-flowing, ideal fluid.
What is Bernoulli’s Equation?
While most pokemon starters evolve for the first time at level 16 there are a few that do not. Name 2 of the pokemon who do not.
Totodile and Turtwig (lvl 18), Cyndaquil and Chimchar (lvl 14), and Tepig or Hisuian starters (lvl 17)
An open container holds a fluid of density p. This is the mathematical expression for the absolute pressure at a depth h below the surface, accounting for the atmosphere above.
What is P =P0+pgh? (where P0 is atmospheric pressure)
Named after a French mathematician, this principle states that a change in pressure applied to an enclosed incompressible fluid is transmitted undiminished to all portions of the fluid.
What is Pascal’s Principle?
A cube is submerged in water. While the pressure on the bottom face is greater than the top face, the net force is known by this term, which is the upward force that opposes gravity.
What is the Buoyant Force?
According to Bernoulli’s Principle, as the velocity of a moving fluid increases, this property of the fluid must decrease (assuming height remains constant).
What is Internal Pressure?

What are the Names of the new starter trio in Generation 10
Browt (Grass-type angry chick), Pombon (Fire-type Pomeranian puppy), and Gecqua (Water-type gecko
During an experiment, a flexible spherical balloon containing air is compressed. During the compression, the volume of the balloon decreases, but the balloon maintains its spherical shape and the number of gas atoms inside the balloon is constant. Which of the following correctly indicates how the density of the gas changes, if at all, as it is compressed?
The density of the gas will increase because the mass of the gas is constant and the volume of the balloon decreases.
This type of pressure is defined as the total pressure at a certain depth, including the pressure exerted by the atmosphere above the fluid.
What is Absolute Pressure
What is four times faster (or 4x)?
If a horizontal pipe’s radius is doubled while maintaining a constant mass flow rate, the velocity of the fluid will change by this specific factor.
What is one-fourth (or 1/4)?
This type is only weak to Ground and Psychic, and resists Bug, Grass, Fighting, Normal, Rock, and Steel
What is Poison?

A cylindrical container is filled with water of density 1000kg/m3 to a depth of .05m. If the container holds .40kg of water, the radius of the container is most nearly
.05m
As fluid speed increases in a horizontal pipe, this fundamental principle states that the pressure within the fluid must decrease.
What is Bernoulli’s Principle?
A block of wood is floating in water. If an identical block is placed on top of it, the buoyant force acting on the system will increase by this amount according to Newton's Laws and Archimedes' Principle.
What is an increase equal to the weight of the second block?
Derived from Bernoulli’s Equation, this theorem states that the speed of a fluid exiting a small hole at a depth h below the surface of an open tank is the same as the speed an object would reach in free-fall from that same height
What is Torricelli’s Law (or Torricelli's Theorem)?
This Pokémon was actually the first one designed, not Pikachu
What is Rhydon?
