..... “Wahai Tuhanku, ilhamkan daku supaya tetap mensyukuri akan nikmatMu yang engkau kurniakannya kepadaku dan kepada dua ibubapaku, dan supaya aku tetap mengerjakan amal soleh yang Engkau redhai; dan jadikanlah sifat-sifat kebaikan meresap masuk kedalam jiwa zuriat keturunanku. Sesungguhnya aku bertaubat kepadaMu, dan sesungguhny...a aku dari orang-orang Islam (yang tunduk patuh kepadaMu)” (Al-Ahqaf 46:15)

A journey to MSSM

Minggu ni memang busy... sebok buat kerja2 perkeranian... best jugak timba pengalaman jadi manager utk team negeri... after 8 years terlibat ngan netball peringkat sekolah and peringkat daerah... this year I berpeluang bawak team Negeri... best2... walaupun penat banyak... tapi tak pe... last year dah terlepas pi Melaka, sebab masa tu baby kecik lagi... this year tak mau terlepas lagi... sorry ye Papa kena ngasuh anak2... kesian pulak kat anak2...

1st day... 27/5/2010
pendaftaran... jam 5.15 ptg dah start dah 1st training...
kehadiran... alamak... memalukan sungguh player Daerah sendiri yg tak cukup... player lain semua dah ada... kecuali seorang player from Bukit Jalil...

best jugak tengok kebolehan budak2 ni... cara passing bola... cara terima bola... pergerakan tubuh... body tinggi lampai semuanya... tu baru kat sini... bila dah kat Putrajaya nanti... player semua tinggi melayut... tak tau lah camna GD/GK kami nak guard GA/GS yg tinggi2 semuanya tuuuuu... kena fikirkan cara...
Latihan hari pertama... U18 vs U15...
Centralised training mula 27/5/2010 - 4/6/2010
6/6/2010 bertolak ke Putrajaya...
game mula 7/6/2010 - 10/6/2010...
wish us luck!!!...
chaiyok!... go fight win!!!

SCALARS AND VECTORS

SCALARS AND VECTORS
  • Vectors are quantities which have magnitude and direction.
  •  Example: velocity, displacement, acceleration, force, electric field strength and momentum.
  •  Scalar are quantities that have magnitude only.
  •  Example: mass, temperature and density.

Addition and subtraction of vectors
  •  A vector may be represented by an arrow.
  •  The addition of two vectors P and Q is a new vector, that is resultant vector.
  •  The resultant vector can be determined using :
             i. method of parallelogram of vectors.
            ii. Method of triangle vectors.
  •   Subtraction of vectors is done by using the process of addition.

Triangle of vectors
1. Use a possible scale to draw vector P.
2. From the head of vector P draw a line to represent the vector Q.
3. Complete the triangle. The line from the tail of vector P
    to the head of vector Q represents the sum (P + Q) in magnitude and
    direction.


Relative velocity

  •   Subtraction of vectors is used to find the relative velocity between two objects.
  •  with velocities vA = 5 m s-1  and vB = 3 m s-1 respectively.
  •   A passenger in car B sees car A in front of it moving away at a speed 2 m s-1.
  • Velocity A relative to B = VA- VB 
  • A passenger in car A sees car B moving backwards at a speed of 2 m s-1.   
  • Velocity B relative to A  = VB- VA 


Resolving a vector

  • The two mutually perpendicular components of a vector R are of magnitude;

                               Rx = R cos θ
                              Ry = R sin θ

PHYSICAL QUANTITIES AND UNITS


PHYSICAL QUANTITIES
  1.   Physical quantities are quantities that can be measured.
  2.   Examples : length, mass, time, weight, electric current, force, velocity and energy.
  3.   To describe a physical quantity, two things must be specified: a numerical value and the unit. 

SI UNITS
  1. The unit of a physical quantity is the standard used to compare different magnitudes of the same physical quantity.
  2. In SI, each physical quantity has only one unit. Prefixes are attached to SI units.
