Our eyes are good at detecting movement. We notice even quite small movements out of the corners of our eyes. It's important for us to be able to judge movement -think about crossing the road, cycling or driving, or catching a ball.

Figure 1. This is a stroboscopic photograph of a boy juggling three balls. As he juggles, a bright lamp flashes several times a second so that the camera records the positions of the balls at equal intervals of time.

If we knew the time between flashes, we could measure the photograph and calculate the speed of a ball as it moves through the air. If you look at the speedometer in a car, it doesn't tell you the car's average speed; rather, it tells you its speed at the instant when you look at it.

This is the car's instantaneous speed. The photograph Figure 1. The time on the clock in the photograph enables us to work out his average speed. If the object is moving at a constant speed, this equation will give us its speed during the time taken. If its speed is changing, then the equation gives us its average speed. Average speed is calculated over a period of time. Therefore, speed is in metres per second. There are many other units used for speed. The choice of unit depends on the situation.

You would probably give the speed of a snail in different units from the speed of a racing car. The runner ran 10 m, and the clock shows the total time taken. Calculate his average speed during the race. Amplitude is measured in metres. The greater the amplitude of the wave, the louder the sound or the rougher the sea!

Wavelength is usually measured in metres. It is the time taken for a point to move from one particular position and return to that same position, moving in the same direction.

It is measured in seconds s. For sound waves, the higher the frequency of a musical note, the higher is its pitch. Sound is one example of such a wave. Other cases are waves on strings, seismic waves and water waves Figure Some properties of these waves are given on page in Table BOX Figure A microphone is connected to the input of the c.

Sound waves are captured by the microphone and converted into a varying voltage which has the same frequency as the sound waves. This voltage is displayed on the c. It is best to think of a c. To do this, its spot moves across the screen at a steady speed, set by the time-base control.

At the same time, the spot moves up and down according to the voltage of the input. Hence the display on the screen is a graph of the varying voltage, with time on the horizontal x-axis. If we know the horizontal scale, we can determine the period and hence the frequency of the sound wave. Worked example 1 shows how to do this. In Chapter 15 we will look at one method of measuring the wavelength of sound waves. Kinetic energyAs well as lifting an object, a force can make it accelerate.

Again, work is done by the force and energy is transferred to the object. In this case, we say that it has gained kinetic energy, E k.

The faster an object is moving, the greater its kinetic energy k. To determine the e. E, we need to find the rate of change of magnetic flux; in other words, the change in magnetic flux per second. Step 2 Use Faraday's law to determine the e. A search coil of wire having turns and of area 1.

The flux density of the field is 0. The coil is pulled rapidly out of the field in a time of 0. What average e. Step 1 When the coil is pulled from the field, the flux linking it falls to zero.

We have to calculate the magnetic flux linking the coil when it is in the field. Hence a On a copy of Figure Describe the changes in the standing wave pattern.

The water level is lowered until resonance is first heard. Calculate the speed of the sound wave. The frequency of the vibrator is adjusted until the standing wave shown in Figure Other SI unUsing only seve of quantities ha would be confu units were also were defined as of water would unlikely that th exactly the mas kilogram, whic which all mass All other un is done using th speed is define speed in the SI Since the de units for force Equations t same base unit not happen the When each te the equation Base units, derived unitsThe metre, kilogram and second are three of the seven SI base units.

These are defined with great precision so that every standards laboratory can reproduce them correctly. Some derived units, such as the newton and the joule, have special names which are more convenient to use than giving them in terms of base units. The definition of the newton will show you how this works. Defining the newtonIsaac Newton played a significant part in developing the scientific idea of force.

For this reason, the SI unit of force is named after him. As we move into studying electricity, we will need to add another base unit, the ampere. Heat requires another base unit, the kelvin the unit of temperature. Table 3. Remember that all other units can be derived from these seven.

Base unitactivity The rate of decay or disintegration of nuclei in a radioactive sample. Avogadro constantThe number of particles in one mole of any substance 6.

The amount of information stored by a device that exists in only two distinct states, usually given as the binary digits 0 and 1. Boyle's law The pressure exerted by a fixed mass of gas is inversely proportional to its volume, provided the temperature of the gas remains constant. Charles's law The volume occupied by a gas at constant pressure is directly proportional to its thermodynamic absolute temperature. Glossary Describing movementOur eyes are good at detecting movement.

Determining speedYou can find the speed of something moving by measuring the time it takes to travel between two fixed points. For example, some motorways have emergency telephones every m. Using a stopwatch you can time a car over this distance. Note that this can only tell you the car's average speed between the two points. You cannot tell whether it was increasing its speed, slowing down, or moving at a constant speed.

BOX 1. Each can be adapted to measure the speed of other moving objects, such as a glider on an air track, or a falling mass. Measuring speed using two light gatesThe leading edge of the card in Figure 1.

This starts the timer. The timer stops when the front of the card breaks the second beam. The trolley's speed is calculated from the time interval and the distance between the light gates. Measuring speed using a ticker-timerThe ticker-timer Figure 1. This is because it works with alternating current, and in most countries the frequency of the alternating mains is 50 Hz.

The pattern of dots acts as a record of the trolley's movement.

Молодой криптограф загнал себя в угол, а от противника, загнанного в угол, можно ожидать чего угодно: он действует отчаянно и непредсказуемо. Стратмор знал, что его следующий шаг имеет решающее значение. От него зависела жизнь Сьюзан, а также будущее Цифровой крепости. Стратмор также понимал, что первым делом нужно разрядить ситуацию. Выдержав паузу, он как бы нехотя вздохнул: - Хорошо, Грег.

Эта организация создавалась с единственной целью - обеспечивать безопасность страны. При этом дерево иногда приходится потрясти, чтобы собрать подгнившие плоды. И я уверена, что большинство наших граждан готовы поступиться некоторыми правами, но знать, что негодяи не разгуливают на свободе. Хейл промолчал.

Он неохотно выполз из-под компьютера. - Побойся Бога, Мидж. Я же сказал тебе… - Но это была не Мидж.

Беккер шел, низко опустив голову. Халохот прокручивал в голове дальнейшие события. Все было очень просто: подойдя к жертве вплотную, нужно низко держать револьвер, чтобы никто не заметил, сделать два выстрела в спину, Беккер начнет падать, Халохот подхватит его и оттащит к скамье, как друга, которому вдруг стало плохо. Затем он быстро побежит в заднюю часть собора, словно бы за помощью, и в возникшей неразберихе исчезнет прежде, чем люди поймут, что произошло.

 У м-меня его. Беккер покровительственно улыбнулся и перевел взгляд на дверь в ванную. - А у Росио.

 - Я понял, что Цифровую крепость не следует останавливать. Сьюзан смотрела на него в растерянности. Стратмор продолжал: - Внезапно я увидел в Цифровой крепости шанс, который выпадает раз в жизни.

Чаша была уже совсем близко, когда Халохот заметил человека в пиджаке и брюках разного цвета. - Estas ya muerto, - тихо прошептал он, двигаясь по центральному проходу. Ты уже мертвец.

Единственным освещением в шифровалке был разве что свет звезд над их головами, едва уловимое свечение проникало также сквозь разбитую стеклянную стену Третьего узла. Стратмор шагнул вперед, нащупывая ногой место, где начинались ступеньки узенькой лестницы. Переложив берет-ту в левую руку, правой он взялся за перила.

 Понятно. Она получит ваше письмо утром. - Спасибо, - улыбнулся Беккер и повернулся, собираясь уходить. Консьерж бросил внимательный взгляд в его спину, взял конверт со стойки и повернулся к полке с номерными ячейками.

Почему. Сьюзан охватила паника. Она быстро проверила отчет программы в поисках команды, которая могла отозвать Следопыта, но ничего не обнаружила. Складывалось впечатление, что он отключился сам по .
