Benchmark 2 Flashcards
This is energy of position; it increases with height
Gravitational Potential Energy
SI unit for measuring any type of energy
Joule
Travels in compressional waves; has to have a medium can cause deafness
Sound Energy
Fusion/Fission; involves either smashing atoms together to make larger atoms, or splitting the atom apart into 2 smaller atoms
Nuclear Energy
Energy of motion; causes objects to move
Kinetic Energy
Heat; Q=mc^t
Thermal energy
Energy stored in chemical bonds; photosynthesis or respiration in animals are examples
Chemical potential energy
Energy that travels in transverse waves across space; carries light and heat
Radiant energy
This explains that the particles of matter move and the warmer the temperature, the quicker the particles move
Kinetic theory of matter
State of matter where particles move extremely fast, loses electrons and produces it’s own light and heat
Plasma
This state of matter has a definite volume, but it takes the shape of its container
Liquid
The temperature at which the motion of atoms particles and electrons stops
Absolute zero
State of matter that has an indefinite volume indefinite shape and particles spread apart dorm each other quickly
Gas
State of matter with particles close together, moving in fixed positions hold it’s own shape
Solid
The buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object explains why an object will sink or float
Archimedes principle
The faster a fluid flows the less pressure the slower a fluid flows the graters the pressure explains why airplanes fly
Bernoulli principle
This equals force divided by area
Pressure
The amount of a liquid normally measured in mL or L
Volume
This equals mass divided by volume
Density
Hydraulic machines work in accordance with this principle abor the pressure of fluids; when pressure is applied to a fluid it spreads throughout the fluid
Pascals principle
The upward force exerted by a fluid that helps an object float
Buoyancy
When you squeeze the coils of a spring or slinky together you create this type of wave
Compressional
The material that a wave is traveling through
Medium
The distance from crest to crest or trough to trough on a transverse wave
Wavelength
These type of waves have the ability to move through outer space
Transverse
What type of waves are water waves or seismic waves
Both compressional and transverse
This determines the height of the wave and the amount of energy a wave carries
Amplitude
The number of wavelengths that pass a fixed point each sound; how often a wave occurs
Frequency
This happens when 2 crest overlap or 2 troughs overlap producing a bigger wave
Constructive interference
Lenses do this well; they bend light
Refeaction
This will decrease if the intensity of a sound wave decreases
Loudness
This happens when the crest of one wave crosses the trough of another wave
Destructive interference
This will change if a waves travels from a less dense medium to a more senses medium
Wave speed
This involves the bending and splitting of light waves into a rainbow
Diffraction
Mirrors do this well; they take light waves and make them bounce back to create an image
Reflection
Underwater system that uses reflection of sound waves to locate depths
Sonar
Results from the combination of the 3 primary colors of light
White
The less dense region where the coils are far apart in a compressional wave
Rarefaction
The three primary pigments of colors
Magenta cyan yellow
The three primary colors of light
Red green blue
This is the result of blending the three primary pigments
Black
The dense region where the coils are close together on a compressional wave
Compression
