Term
 momentum equation
Definition
 p=mv
Term
 impulse
Definition
 change in momentum. J=delta p= m delta v. Or, J=Ft
Term
 Power=
Definition
 P=Work or Energy over time; P=Fv
Term
 PEspring
Definition
 1/2kx^2
Term
 Force of spring
Definition
 Fs=kx
Term
 Equations involving n- index of refraction
Definition
 n1sinX!=n2sinX2; n=c/v
Term
 Continuity Eqn (fluids)
Definition
 A1V1=A2V2
Term
 Bernoulli's equation
Definition
 P1+pgh1+1/2pv1^2=P2+pgh2+1/2pv2^2
Term
 Buoyant Force
Definition
 Fb=pVg
Term
 Internal Energy
Definition
 Delta U=Q+W; Delta U=3/2nR delta t
Term
 Carnot Efficiency
Definition
 ec=(Th-Tc)/Th
Term
 Temp is proportional to..
Definition
 molecular speed squared
Term
 Elec & Mag: Force, Voltage, Power, Current
Definition
 F=qvB; V=IR; P=VI=V^2/R=I^2R; I=Q^2/t (Coulomb/sec)
Term
 Isothermal
Definition
 Temp remains constant
Term
Definition
 Delta U= 0
Term
 Isobaric
Definition
 Pressure remains constant
Term
 Isochoric
Definition
 Volume remains constant- system does no work- Delta U=Q=nCdeltaT
Term
 Zeroth Law of Thermodynamics
Definition
 If objects 1 and 2 are each in thermal equilibrium w/ Object 3, then they are in te w/ each other. Heat will flow from warmer obj to cooler until they reach te.
Term
 First law of Therm
Definition
 Delta U= Q + W. Delta U depends on temp change, assuming no phase change.
Term
 2nd Law of Therm
Definition
 For any cyclic heat engine, soem exhaust heat also produced. Its impossible to have 100% effeciency.
Term
 Kirchhoff's Rules
Definition
 Loop Rule- sum of potential differences that traverse any closed loops in a circuit must be 0. Junction Rule- Total current that enters a new junction must = total current that leaves. (Node Rule)
Term
Definition
 Magnitude of emf induced in a circuit=rate of change of magnetic flux through circuit. EMF=delta magflux/delta t
Term
 Magnetic flux
Definition
 magflux=BAcosX
Term
 Pascal's Law
Definition
 Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.
Term
 Newton's 1st Law
Definition
 Law of Inertia- obj will continue in state of motion unless force stops it
Term
 Newton's 2nd Law
Definition
 F=ma
Term
 Newton's 3rd Law
Definition
 To every action, there is an = but opposite reaction.
Term
 Deuteron
Definition
 One p+, one neutron
Term
 Deuteron
Definition
 One p+, one neutron
Term

Definition
 charge +1, same mass as electron.
Term
 alpha particle
Definition
 helium nucleus- 2 p+, 2n
