27 Lecture Notes 1 Units of measurements, calculaoons When we report a measurement we report Number Unit

28 Units of Measurements ReporOng the measurement of a quanoty without giving its unit is meaningless For example saying that the length of a race is 3 means nothing without the associated unit, say km or miles There are many different units for the same property Length could be angstroms, cenometers, meters, inches, feet, miles, light years, etc

29 SI units mass kilogram length meter kg m Ome second s temperature Kelvin K amount mole mol current ampere A

30 EssenOally all science and engineering use the System InternaOonal or SI system Base SI Units Quan:ty unit symbol Mass kilogram kg Length meter m Time second s Temperature degree K Amount mole mol Current ampere A

31 Common derived units: velocity = length / time = m s 1 acceleration = velocity / time = ms 2 force = mass x acceleration = kg m s 2 = Newton N Energy = Force x distance = Nm = kg m 2 s -2 = Joule J pressure = force / area = N / m 2 = kg m -1 s -2 = Pascal = Pa frequency = 1/ time = s -1 = Hertz = Hz

32 Oqen powers of 10 are represented by a prefix prefix pico (p) micro (μ) milli (m) Value kilo (k) 10 3 mega (M) 10 6

33 7.0 picometers 7.0pm 7.0 x m 8.6 micrometers 8.6μm 8.6 x 10-6 m 12.6 kilometers 12.6km 12.6 x 10 3 m

35 Significant figures How many significant figures are in a number? 1. If there is a decimal point in the number, draw an arrow from leq to right unol you come to the first non- zero digit. All digits you did not draw through are significant significant figures 4 significant figures

36 2. If there is no decimal point in the number draw an arrow from right to leq unol you come to the first nonzero digit. All digits you did not draw through are significant. However this is the minimum number of significant figures in the number. You cant tell about the zeros unless the number is wri_en in scienofic notaoon At least 3 significant figures Perhaps 5

37 ScienOfic NotaOon Represent numbers as a number between and muloplied by a power of = x 10 = 2.71 x = = x 10 4
