Unit 5 Flashcards
aerodynamics
the study of the movement of air
amplitude
half the height of the wave
calorimetry
the science of measuring heat
closed system
a system that does not interact with other systems or one that is contained
crest
the highest point of a wave
density
the mass per unit of volume
diffraction
a change in the direction of waves that occurs when a wave encounters an object
equilibrium
balance
flow
the reaction of fluids to their surrounding environment
flow velocity
the speed of flow of a liquid
fluid dynamics
the study of liquids and gases in motion
frequency
the number of waves that pass a given spot over a set period of time
hydrodynamics
the study of the movement of water
hydrostatic pressure
the pressure created by the equilibrium of fluid because of the forces of gravity
interference
the reaction of waves of the same medium when they interact with each other
lake turnover
the seasonal process through which the water of a lake becomes stratified and remixed
period
the time it takes a complete wavelength to pass a designated point
physics
the study of matter and energy
pressure
the force per unit area
reflection
the reversing of the direction of a wave when it bounces off an object
refraction
the bending of waves when they pass through a surface
rogue waves
constructive waves that are greater than twice the size of those around them
static
without movement, still
trough
the lowest point of a wave
velocity
the speed of the wave and also often includes the direction in which it is traveling
wave base
the water under the wave impacted by its movement
wavelength
the distance between one wave and the next
