Density
What is the equation to find density
d = m/v
In a solid, these particles are packed closely together and are not free to move about within the substance.
Rate these fluids based on what has a higher viscosity to low viscosty
Honey
Water
Peanut butter
Milk

What are the 2 forcees acting on an object as it enters water?
Gravity and Buoyancy
What does pressure mean?
What are the units for density for solids and fluids?
g/cm3 for solids, g/mL for fluids
What are the molecules like in a liquid?
In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another.
What is viscosity?
What is Archimedes Principle?
When an object is placed in water and it displaces water.
What does compressibility mean?
The ability of something (such as a fluid) to be reduced in volume or size under pressure.
What is density?
Mass per unit volume.
What are the molecules like in a gas?
What is Flow rate?
Is wood a positively buoyant object?
Yes.
What does hydraulics and pneumatic mean?
Hydraulics is a mechanical function that operates through the force of liquid pressure
Pneumatic means filled with or operated by compressed air. In general, pneumatic means related to air or wind.
What are the 3 formulas used for density?
D = M ÷ V
M = D x V
V = M ÷ D
How are liquids different from solids? Give 3 examples
1. A solid is a state of matter that has a definite shape and volume. A liquid is a state of matter that has volume but no definite shape.
2. A liquid takes the shape of the container that holds it. A solid has a shape of its own.
3. Solids are strong, tough, elastic, ductile, and flexible. liquids are not.
The 3 factors that affect flow rate are?
temperature, size of particles and internal friction.
Is Rock a positively buoyant object?
No
What is the equation to find pressure?
P = F/A
P= Pressure
F = Force
A = Area
What is average density?
Whats heavier 20 pounds of bricks or 20 9.07 liters of water?
Neiter they are the same!
(Volume over time) or (ml over s) is what equation?
to determine the flow rate
Do hot air balloons have buoyancy?
Yes.
How is Pascal's Law connected to hyraulics?
Pressure gets equaly sent out.
