Cards in this set: 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 Adiabatic 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 Faraday's Law of Electromagnetic Induction 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 positron Definition charge +1, same mass as electron. Term alpha particle Definition helium nucleus- 2 p+, 2n
