Cards Term adiabetic system Definition a system in a state of thermal isolation, no heat transferred Term adiabetic process Definition no heat transferred Term conservative force Definition the work it does, when its point of application moves from one point to another, os independent of the route followed between those points Term faraday's law Definition the magnitude of the induced EMF around the boundary of its surface is equal to the |derivative of magnetic flux| through that surface Term explain the born interpretation Definition the wavefunction of a partical determined the probability of findingthe partical in a given region Term boson Definition partical that has zero spin and does not obey the pauli exclusion principle Term fermion Definition particle with half integer spin that obey the pauli exclusion principle Term derivative Definition for a given function f(y) it is the rate of change of f(y) with respect to y Term conservative force Definition the work it does when its point of application moves from one point to another, is independent of the route followed between those points Term simple harmonic motion Definition a form of oscillatory motion about an equilibrium position, the acceleration is always directed towards the equilibrium position and proportional to the displacement from that point Term conservation of angular momentum Definition the total angular momentum about any point remains constant as long as no net external torque about that point acts on that system Term PVT surface Definition for an ideal gas P represents the pressure V represents the volume and T represents the temperature they characterize the equilibrium states odf a given macroscopic system Term vector field Definition a quantity that can have a definite magnitude and direction ascribed to it at every point, i.e electric field. Term Lorentz transformation Definition coordinate transformation of special relativity.if an event occurs in frame of reference A then the coordinates of the same event in frame of refernece B is x'=x-Vt/sqrt(1V^2/c^2) t'=t-(Vx/c^2)/sqrt(1-V^2/c^2) wher V is the relative speed of B with respect to A Term de Broglie formula Definition the equation lambda=h/p for the de broglie wavelength of a material in terms of planks constant,h, and the magnitude of the (relativistic) momentum,p, Term de Broglie wavelength Definition the wavelength which de broglie's theory of wave particle duality assigns to a material particle of given momentum Term binding energy of a nucleus Definition the least amount of energy required to seperate a system into its components Term Kepler's laws Definition three laws describing the motion of the planets around the sun 1. the orbit of each planet is an ellipse with the sun at one focus 2. a radial line from the sun to a planet sweeps out equal areas in equal intervals of time 3. the square of the orbital period of each planet is proportional to the cube of its semimajor axis Term Newtons law of universial gravitation Definition every particle of matter attracts every other particle of matter with a gravitational force whose magnitude is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them
