  1. SOALAN 1 • kgm s-2(mass x acceleration = force ) • kgm s-1(mass x velocity = momentum ) • m s-1 • m (Distance (m) = velocity x time )

  2. 760.3 cm SOALAN 2 759.6 cm 760.3 cm - 759.6 cm = 0.7 cm

  3. SOALAN 3 RV against MV Responding Variable (RV) (Pembolehubahbersandar) Gradient = -10 Manipulated Variable (MV) (Pembolehubahdimanipulasi)

  4. CATATAN Y is increases linearly with X (Y bertambahsecara linear dengan x) Y is inversely proportional to X (Y berkadarsongsangdengan x) Y is directly proportional to X (Y berkadarterusdengan x)

  5. Vernier calliper Angkup vernier 2 cm 1 cm 0 0 cm 0 10 SOALAN 4 • 0.5 cm + 0.05 cm = 0.55 cm Main scale reading = 0.5 cm ( 0.0 < 1.0 → 0.5cm ) →( 0.05cm ) Vernier scale reading = 0.05 cm

  6. Red fringe Pinggir merah Dark fringe Pinggir gelap 32.0 mm SOALAN 5 x x x SOALAN 8

  7. SOALAN 6 Constant Acceleration (Pecutanseragam) Increasing Acceleration (Pecutanbertambahtidakseragam) Decreasing Acceleration (Pecutanberkurangtidakseragam) Constant Velocity (Halajuseragam)

  8. Inclined plane Landasancondong Block Bongkah SOALAN 9 Normal Reaction Rough surface Surface of contact (satahsentuhan) Weight SOALAN 10 Net force = 0 N (no movement/const. velocity) Net force = upward ( accelerate upwards) Net force = downward ( accelerate downwards) Net force = 500N – 400N = 100N F = ma → a =

  9. SOALAN 12 Force parallel to distance moved = 10cos 40o Distance moved = 5m Work done = 10 cos 40o x 5 = 38.3 J

  10. SOALAN 13

  11. SOALAN 16 Low air speed, High air pressure Slightly highair speed, slightly lowair pressure Very highair speed, Very lowair pressure

  12. C. A. B. SOALAN 18 Low air speed, High air pressure (Pushes the water down) Slightly highair speed, slightly lowair pressure Very highair speed, Very lowair pressure (Pushes the water level down slightly)

  13. SOALAN 23 Speed of wave, v = f = 25,000 Hz x 4.8 x 10-2m Distance, s = vt = 25,000 Hz x 4.8 x 10-2 m x 0.4s = 42o SOALAN 24
