Exercises
1, Listen, read and translate the text.
2. Answer the following questions in a written form:
1. What do we need to make any measurement? 2, How. do we measure the length of a table? 3. What unit does а physicist use to measure the weight of a body? 4. What is the unit of volume?
3. Make up and write 8 sentences using the words given in the table:
.....
We The metre. A trained physicist The gramme The students The litre |
study made will measure uses is prepared |
the unit of weight. properties of matter. the unit of volume. different units. the unit of length. physical phenomena. some measurements. |
4. Translate the following sentences and explain the use of tenses in them:
1. We are familiar with the idea that measurement requires a system of units. 2. In present-day England, for example, amounts of money are measured in pounds, shillings and pence, though there is talk of using a decimal system. 3. For scientific and engineering purposes there are three quantities of fundamental significance. 4. These are mass, time and length. 5. We must learn these units of measurement. 6. An object possessing mass will resist any change we try to make in its motion. 7. Until recently the meter was defined as the distance between two marks on the particular platinum-indium bar kept at the International Bureau of Weights and Measures at Sevres in France. 8. The instrument chosen to measure any given length depends on the magnitude of the length and the accuracy to which the measurement is required.
5. Copy the following sentences putting "in, into, from, through, of, to, by" in the blanks:
1. The pencil is ... the box. 2. I go ... the reading-room 3. We take books ... the library. 4. Moscow is the capital .. our country. 5. An electric current passes... the wire ... an iron. 6. He came ... the room. 7. We heat an iron ... an electric current.

7. Make up and write all possible questions to the following sentences:
1. In England the fundamental unit of length is the yard. 2. In France, on the other hand, the standard of length is the metre, rather more than the yard. 3, We need some fixed quantity called a unit to make measurement.4. The Egyptians used primitive water clocks and sand glasses.
8. Copy these sentences putting "unit", "size", "measurements", "volume", "deals", "quantity", "trained", "property", "use" in the blanks:
1. Every ... physicist makes many measurements. 2. We measured the ... of the room last time, 3. What do you use to measure the... of milk? 4. Physics... with many phenomena. 5.

9. Substitute the infinitive by the proper form of the verb:
1. Scientists (to discover) the laws of physics by the experimental method. 2. These experiments (to involve) accurate measurements of various quantities. 3. There (to be) three quantities of fundamental significance. 4, Before the fourteenth century, the movements of shadows cast by the sun on sundials (to provide) time.
