Rolling without slipping
v=R, a=R
Maybe some students are not so clear about the difference between the formula of rolling
without slipping and the formula of circular motion. They look very similar, but their meanings
are different

Physics 1B Practice Midterm 2 Solutions
(1) The work W done by the gas during the cycle is determined by the are of the P V diagram bounded
by the cycle, i.e. the area of the trapezoid (see figure below). Note that the diagram is only schematic

Physics 1B Midterm 1 Solutions
(1) The density of ice at the freezing point is less than that the density of the water at the same
point. This is counterintuitive as most materials become denser upon solidification. Assume that the
density of ice is given

(1) Suppose that n moles of an ideal monatomic gas perform a cycle shown in figure. The order of
the steps is 1-2-3-4-1. Determine the work and heat exchange in this cycle, in terms of P0 , P1 , P3 and
V1 , V2 . (Pi , Vi are
