Period (T) = seconds 


Term

Definition
Fspring = kx
x is the stretched length of the spring
k is spring constant (N/m) 


Term
Relationship between period and physical properties of a simple harmonic oscillator 

Definition

m = mass
bigger the mass the slower it goes

vs.
vibrate in a direction parallel to the medium 


Term

Definition
v = (lambda)f
[[aka v = wavelength x frequency]]
(m/s)
lambda = wavelength
f = frequency 


Term
What does the speed of a wave depend on? 

Definition
THE SPEED OF A WAVE DEPENDS ON ITS MEDIUM
((It's independent of wavelength and frequency))
speed of wave depends (sqroot Force Factor/ Mass of something) 


Term
What does the frequency of a wave depend on? 

Definition
THE FREQUENCY OF A WAVE DEPENDS ON ITS SOURCE 


Term
Antinodes vs Nodes in waves 

Definition
antinodes = loops
nodes = points of no displacement between loops 


Term
Linear Expansion of Solid (like heating) 

Definition
(delta L) = (alpha)(Lo)(delta T)
Delta L = Change in Length
Alpha = type of stuff...bigger alpha, faster things change temperature
Lo = original length
Delta T = change in temperature 


Term
Ideal Gas Law formulars

Definition


Term
Root Mean Square Velocity

M = molar mass of gas
miew = mass/molecule of gas 


Term

Definition
Q = mc(delta T)
Q = transfer of energy due to difference in temperature
c = specific heat 


Term

Definition
U = 3/2NkT
N = number of molecules
kT = average energy per molecule 


Term
Conduction
(transfer of thermal energy through physical contact) 

Definition
H = (Delta Q)/ (Delta time)
or
=kA(delta T)/L
A=area
L = Length through which heat is being transfered 


Term

Definition
heat transfer through the movement of a fluid 


Term
First Law of Thermodynamics
Change in internal energy can be either negative or positive.
If (deltaU >0) the energy in the system increases, if opposite the energy in the system decreases


Definition
(delta U) = Q + W
W = P(deltaV)
If work is done ON the system, W > 0
If work is done BY the system, W < 0
I have U; I do W; and Q flows into me 


Term
Thermodynamic Processes
Isothermal 

Definition
keeps the temperature constant
(delta T) = 0
(delta U) = 0
SO Q = W
PV = nKT 


Term
Thermodynamic Processes
Adiabatic


Definition
no heat flows
(Q = 0)
happens when something is done super fast 


Term
Thermodynamic Processes
Isobaric


Definition
Constant Pressure but change in volume
Q = (delta U) + W 


Term

Ideal efficiency 

Definition
e = W/Qh
W = how much work you can do
Qh = how much heat you can take out
Ideal  e = 1  TL/TH
