  1. 1. Straight motion
  2. 2. Let’s look the picture
  3. 3. Let’s look the picture
  4. 4. Let’s look the picture Old position Old position New position New position A B Can you tell me about rockets A and rockets B!
  5. 5. Let’s look the picture Old position Old position New position New position A B We can say, rocket A moving and B No ! Moving object is identified by its change of position from a certain point of reference
  6. 6. A change of position or displacement of an object from a certain point of reference is called MOTION
  7. 7. In the lesson you are abble to : <ul><li>Making a graph of displacement vs time </li></ul><ul><li>Finding the equation of speed </li></ul><ul><li>Identifying the application of constant straight motion in daily life </li></ul>
  8. 8. Science key word <ul><li>Speed </li></ul><ul><li>Velocity </li></ul><ul><li>Acceleration </li></ul><ul><li>Point of referent </li></ul><ul><li>Motion </li></ul><ul><li>Average speed </li></ul><ul><li>Straight motion </li></ul><ul><li>distance </li></ul><ul><li>Laju </li></ul><ul><li>kecepatan </li></ul><ul><li>Percepatan </li></ul><ul><li>Titik acuan </li></ul><ul><li>Gerak </li></ul><ul><li>Laju rata-rata </li></ul><ul><li>Gerak lurus </li></ul><ul><li>perpindahan </li></ul>
  9. 9. Introduce <ul><li>Motion </li></ul><ul><li>Motion is a change of position or displacement of an object within a certain time interval </li></ul>
  10. 10. Various form of motion <ul><li>Straight motion </li></ul><ul><li>Circular motion </li></ul><ul><li>Parabolic motion </li></ul>
  11. 11. <ul><li>Point of referent is location which is considered fixed (at rest) and used to compare the initial and final position. </li></ul><ul><li>To understand how fast the object moves we have to know time needed to travel the distance of displacement. </li></ul>
  12. 12. Velocity <ul><li>Grahp </li></ul>d (m) d2 d1 0 t1 t2 t (s) distance (m) time (s) d1 t1 d2 t2
  13. 13. Velocity <ul><li>Grahp </li></ul>d (m) d2 d1 0 t1 t2 t (s) This Constanta is Called Velocity
  14. 14. Velocity Velocity is the change of position within a time interval If distance (d), time interval (t) and velocity (v), we can write formula of velocity
  15. 15. Velocity The relationship among d, t, and v
  16. 16. Velocity The unit of velocity can be determine by unit of distance divide by unit of time If unit of distance in SI is meter, time interval is second, and velocity is meter per second (m/s). In our daily life we usually use km/h
  17. 17. Velocity <ul><li>Velocity have two components : </li></ul><ul><li>Magnitude (absolute value) </li></ul><ul><li>Direction (arah) </li></ul><ul><li>Speed just have magnitude </li></ul>
  18. 18. Velocity <ul><li>Base on component that contents of quantities, quantities can be derived in two kind : </li></ul><ul><li>Vector </li></ul><ul><li>Scalar </li></ul>
  19. 19. Velocity <ul><li>For example </li></ul><ul><li>If some one walking 5 km/hour toward east : </li></ul><ul><li>a. his speed is 5 km/hour </li></ul><ul><li>b. his velocity is 5 km/hour to east. </li></ul>
  20. 20. Velocity Calculating the velocity Pada kenyataannya setiap object yang bergerak kecepatannya selalu berubah (baik arah maupun nilainya) Tidak mudah untuk memberikan contoh object yang bergerak dengan kecepatan tetap. Untuk menjelaskannya digunakan konsep average speed (kecepatan rata-rata)
  21. 21. Velocity Calculating the velocity Average speed is the total traveled distance divided by the time needed to travel that distance. v = average speed  d = total distance  t = time total
  22. 22. <ul><li>Motion ber-sifat relatif </li></ul><ul><li>Benda dikakatan bergerak atau tidak tergantung dari titik acuan (point of reference) yang digunakan </li></ul><ul><li>For example </li></ul><ul><li>Seseorang yang ber ada dipinggir jalan akan melihat orang-orang yang berada di dalam mobil bergerak, tetapi antara penumpang dan sopir tidak bergerak. </li></ul>
