Exercise 1. a). The text you are going to read is headlined “Mechanics”. Guess what it can run about.
b).Think of 5-7 questions the answers to which you hope to find in the text.
c) In pairs, ask and answer these questions
Exercise 2. Mind the pronunciation of the following words:
kinematics ["k(a)InI'mxtIks] force [fO:s]
dynamics [daI'nxmIks] rigid ['rIdZId]
equilibrium ["i:kwI'lIbrIqm] mathematical [mxTI'mxtIk(q)l]
enunciate [I'nAnsIeIt] acceleration [qk"selq'reIS(q)n]
postulate ['pPstjVlIt] frictional ['frIkS(q)nql]
law [lO:] energy ['enqdZI]
motion ['mqVS(q)n] equality [I'kwPlItI]
particle ['pQ:tIk(q)l] momentum [mq(V)'mentqm]
precision [prI'sIZ(q)n] angular ['xNgjVlq]
relativity ["relq'tIvItI] propulsion [prq'pAlS(q)n]
survive [sq'vaIv] mechanism ['mekqnIz(q)m]
Exercise 3. Guess what the following international words mean.
Classical, to balance, postulate, phenomenon, to formulate, to ignore, approximation, planetary, orbital, kinematics, dynamics, conservation, energy, stress.
Exercise 4. Below you will find a list of physical terms mentioned in the text. Choose their Russian equivalents in the right-hand column.
| motion | çàêîí ñîõðàíåíèÿ |
| force | óãëîâîé ìîìåíò, âðàùàòåëüíûé ìîìåíò |
| equilibrium | äåéñòâèå, âîçäåéñòâèå |
| law of conservation | âçàèìîäåéñòâèå |
| precision | óñêîðåíèå |
| particle | ñèëà |
| interaction | ïîñòóïàòåëüíîå äâèæåíèå, òÿãà |
| dimension | òðåíèå |
| relativity | ðàâíîâåñèå |
| propulsion | äâèæåíèå |
| acceleration | òî÷íîñòü |
| angular momentum | ðàçìåð |
| friction | ÷àñòèöà |
| action | îòíîñèòåëüíîñòü |
Exercise 5. The words in A are used in the text “Mechanics” Choose their definitions from B and translate these words into Russian.
| A | B |
| rigid | the same, not varying in form, quality, etc |
| vague | putting to practical use |
| uniform | to prevent, to hinder |
| application | to say, to tell in advance |
| framework | deep, having great knowledge |
| profound | firm, strict, unbending |
| to predict | that part of a structure that gives shape and support |

Exercise 6. The verbs given below are mostly used with certain prepositions:
| to account | to lead | to be concerned |
| to think | to center | to inherit |
| to act | to deal | to derive |

| to root | to range |
Find the sentences in the text where these verbs are used. Name the verbs with the proper postpositions and give their translation. Think of your own sentences containing these verbs.
Exercise 7. Match nouns and verbs to form collocations. Use each verb and each noun once only.
| to balance | intrinsic properties of bodies |
| to enunciate | the science of statics |
| to predict | an important part |
| to ignore | force |
| to play | one’s energy |
| to undervalue | forces |
| to constitute | basic postulates |
| to determine | centre stage |
| to cancel | a state of rest |
| to achieve | phenomena |
| to hold | limits of structures |
| to sap | one’s importance |
Exercise 8. There are some words given in bold type in the text. Choose their synonyms from the table below. Pay attention that the forms of the words in the text may differ from those in the table.
