7. Slide 7 7 1.Units and Dimensional Analysis We use many quantities in everyday life as: Length – Mass – Time – temperature – Current- Voltage – Power- velocity – etc Quantities that we can measure and express as number are called Physical Quantities

8. Slide 8 2. Physical quantities are divided into: I- basic or fundamentals quantities They can not be expressed in terms of other quantities QuantitiesSymbolUnit LengthLm (meter) MassMkg (kilogram) TimeTs (second) CurrentIA (Ampere) Absolute TemperatureATK (degree Kelvin) Amount of substanceASMol (mole) Luminous intensityLIcd (candela)

9. Slide 9 II- Derived Quantities Are quantities which expressed in terms of the fundamental quantities as: 1.Velocity (v) = length / Time = L / T = m / s. 2. Acceleration (a)= Velocity / Time = (L/T)/ T = L/T 2 = m / s 2 3. Density (D) = mass/volume = M / V = kg /m 3

10. Slide 10 10 4. Force F = mass x acceleration = ma = M (L/T 2 ) = kg.m/s 2 III- Dimensionless Quantities ( with no units) as: 1- refractive index (n) 2- constant Pi (  ) 3- Atomic weight (M)

11. Slide 11 Physical Quantities also classified into :  Scalar Quantity: defined by number only like mass- length- time- density  Vector Quantity: defined by number and direction like magnetic force, weight To measure any quantities there are two requirements: 1- we must have a measuring instrument (direct or indirect) 2- we must have a system unit of measurements

12. Slide 12 There two types of units 1-Gauss Unit (cgs) Length (cm)- mass (gram) - Time (s) 2- System International (SI) Length (m)- mass (kg) - Time (s) In physics, we deal with quantities which are very small to very large from 10 -18 to 10 28

14. Slide 14 3. Vectors A vectors has magnitude as well as direction Vector symbol Properties of Vectors 1.Components of Vector A 2. Magnitude and direction of vector A Example1 Find the two components of vector A A x = A cos  = 10 cos 60 = 5 A y = A sin  = 10 sin 60 = 8.66 A A 10 60

15. Slide 15 Vectors in three directions Vector components Vector magnitude Example 2 Vector A= 4i+2j-4k, find the magnitude IAI? Sol: A x =4, A y = 2, A z =-4 and the magnitude

16. Slide 16 4. Adding Vectors vector added to vector equal vector  By drawing  If and = (A x +B x )i + (A y +B y )j + (A z +B z )k Example: vector A= 3i+5j+2k and vector B= -i+2j-k = (+3-1)i +(+5+2)j + (+2-1) K = 2i + 7j+k

17. Slide 17 Scalar product AB=IAIIBI Cos   changes from 0 o to 90 o  If A and B are parallel i.e  =0, Cos 0=1 AB=IAIIBI 1  If A and B are perpendicular i.e  =90, Cos 0=0 AB=0 2 Vector product AxB=IAIIBI sin   changes from 0 o to 90 o  If A and B are parallel i.e  =0, sin 0=0 AxB = 0 1  If A and B are perpendicular i.e  =90, sin90=1 AxB=IAIIBI 2 5.
