The answer shows how you can present a calculation so that it is easily understood by an examiner or by other people.

The battery's EMF is 6. The resistance R, is chosen so that the bull is run under the conditions for which it was designed, ie. Calculate: a the current that flows through the bulb under the design conditions b the resistance of the bulb under these conditions c the total resistance of the circui 4d the value of the resistance Ry. Answer fa Power P 3. At first you discover which branch of physics is concerned, perhaps electricity or mechanics, You ask yourself whether you have met a similar question before.

Diagrams A diagram contains information that can be seen at a glance and it can be easier to work from than the lengthy wording of a question, Ifa diagram is not provided with a question or asked for, a quick sketch may be worthwhile. Note that the question in our example would have been complete without the diagram. Diagrams can be very helpful For diagrams you will need to be familiar with some symbols such as those for the battery, bulb and resistors that are shown in Fig.

The lines drawn with arrows on them to represent forces are another example. Symbols for electric circuits are Mo. F for force and R for resistance are examples. Greek symbols are often used; the symbol 4 pronounced lambda for wavelength is an example. Using upper case and lower case letters can distinguish between two. Subscripts serve the same purpose, eg.

R, was used for the series resistance in our worked example 1. In Example 3 of Chapter 4 abbreviations f, and A are used for two horizontal forces, similarly V4 and Pq for two vertical forces.

For some quantities many different symbols are used, You will find d, s, x, rand other letters used for distances. Whatever letters you decide upon you must state what they are being used for.

A list of the SE units you will meet is given in Table I on page , Note that the SI unit for resistance measurements is the ohm and its abbreviation is the Greek letter omega. We have already had an example: 8.

Itis customary to write units in the singular. So we sce 3 metre rather than 3 metres. You should adopt this practice in your calculations. However, in text, the plural is acceptable because it makes more comfortable reading. When abbreviations are used 3 joule is written as 35 and we certainly do not put an s after the J here, The J s joule second applies to quite a different quantity.

Write units in the singular in all calculations 3 volt or 3V, not 3 volts All the formulae you learn should work with SI units and all formulae used in this book work with ST units.

Formulae work with SI units Multiples of SI units such as the kilometre km, a thousand times a metre and megawatt a million times a watt may be used when stating the size of a large quantity. Submultiples of the SI units such as the milliampere: a thousandth of an ampere of a centimetre one hundredth of a metre may be convenient for describing small quantities.

A gap must be used when a unit is made up of other units. Thus a newton metre is written as Nm. It is safer to work in whole SI units. For every item you work out you must show the unit. It can be very cumbersome to insert the unit for very quantity every time it is used. So the answer is 1 6. Formulae needed in some questions can be more tedious to transpose and, if the values that are to be put into the equation are not too complicated, it is best to start by entering the data in the formula you remember, Transposition is delayed until the calculation has achieved some simplification.

It was used in part a of our answer. Write a calculation as a series of equations Using your calculator Its assumed that you have an electronic calculator which has keys for sin, eas and tan for use with angles and for the log of a number. So to work out 6. Advice given in this book for calculator use will apply to the Casio frWA calculator. The procedures for switching on this calculator, 4 Fig.

When the small figures are 11, for example, multiplying by 10 eleven times would be inconvenient and this is one reason for keeping the 1. Even when you have a good knowledge of physics and the appropriate maths you can get stuck. Pethaps it is in the list provided with the exam paper. It is a key word. Rough checks are mentioned in Chapter 2 and these wifl minimise errors, Hurrying encourages errors, of course. Leaving a question and returning to it can waste time but may give you a fresh view of a problem and lead to a successful answer.

So take care and good luck with your calculations? A quantity is a number or a measurement. A measurement is a number times a unit, eg. Note that units used in calculations are written in the singular. Abbreviations are used for units, e. Units are discussed in Chapter 3. Fractions A half is obtained by sharing one equally between two or dividing 1 by 2.

Cancelling units features in Chapter 3. The reciprocal of a simple number e. Examples are 3x? If you wanted to add 3. But you can sec at a glance that the answer should be more than 3. What is measured i. Fundamental and derived quantities Several quantities, like mass, length, time, tem ature, are called fundamental or base quantities while others are derived from these.

One example of a derived quantity is a velocity which is a length divided by a time. So the dimensions of a quantity are the base quantities from which it is made up in the same way that the dimensions of a bax would be length, width and depth of the box.

Thus the dimensions of a force are M, L and T-? Some quantities are dimensionless, ie. They are simply numbers, perhaps ratios of similar quantities. An angle is an example an angle in radians equalling an arc divided by radius, i. The symbols Q, J, may be used for the dimensions of charge, current and temperature. This fact can be useful for checking equations. Method We need to relate each of these quantities to quantities whose dimensions are known.

C kg hm tc E kgo'm? Neither of these formulae gives an immediate answer because the volt for V does not appear in the answers suggested. For capacitance we get Cg! Answer D. Now Cheam? As regards checking units, an example of a unit which is difficult to remember is that for thermal conductivity, 4; see Chapter Exercise 3.

I am looking at this text from the viewpoints of both a two semester algebra-based physics course for engineering majors and a one-semester algebra course aimed at students in medical and technology and technology programs. All the standard topics are extensively covered, providing the instructor many options for structuring either course. For a one-semester course, there is ample material to allow the instructor to select the topics and depth of coverage. The text provides links to appropriate simulator activities, from the Ph ET library. The Frontiers of Physics chapter provides a quick view of where Physics is today. Presentation and organization of the text are consistent.
