  • 正面 angular acceleration
    背面 the rate of change of angular velocity with time
  • 正面 center of gravity
    背面 the point where the total weight of the body is assumed to be concentrated
  • 正面 change in angular velocity
    背面 the difference between final and initial values of angular velocity
  • 正面 change in momentum
    背面 the difference between the final and initial momentum; the mass times the change in velocity
  • 正面 conservation of mechanical energy
    背面 the rule that the sum of the kinetic energies and potential energies remains constant if only conservative forces act on and within a system

此牌组在导入时经过修改: Entries were taken from the end-of-chapter glossaries of chapters 7, 8, 9, 10 and gathered into one deck; the chapter structure of the book is not reproduced. HTML formatting was stripped to plain text, and superscripts and subscripts were converted to the corresponding Unicode characters so that a charge or an index is not lost (H⁺, not H+; T₄, not T4). An entry was dropped when its definition is shorter than 30 characters or longer than 400 characters, when it contains an image, a table or a mathematical formula that is not reproduced here, when it refers to a figure, a table or another chapter, when it is dated by wording such as "currently" or "as of", when it is a bare cross-reference to another term, or when a superscript could not be converted faithfully. Duplicates were removed on the term and on the definition alike, both compared after lowercasing, removing parentheses and reducing plurals to singulars; a term or a definition already used by another Memoquiz deck built from OpenStax was dropped as well. Each deck is capped at 150 entries and holds at least 30. The wording of every definition that was kept is unchanged.
