ticker timer & ticker tape slideshow by idrul nafiz

Text of Ticker timer

  • 1.

2. 3. 4.

  • Is a device used to study the motion of an object for a short period of time
  • Vibrating steel strip will vibrate 50 times every second and make 50 dots a second on a tape being pulled through

5.

  • Time interval between 2 consecutive dots ( 1 tick) is 1/50s or 0.02s
  • To calculate time: No. of tickx 0.02s

. . . . 1 dot 1 tick 6. TEST YOURSELF

  • What are the time taken for:

. . . . . . . . . . . . . . 7.

  • Besides time taken ticker timer is also used to determine:
  • Velocity
  • Acceleration
  • Types of motion
  • Distance
  • HOW TO MEASURE VELOCITY? ACCELERATION?

8. DETERMINE VELOCITY

  • How may ticks that you can see?
  • Can you calculate the time taken?
  • What are the distance?
  • Thus:
  • VELOCITY =DISTANCEUNIT??
  • TIME TAKEN

. . . . . . . . . 12cm A B 9. DETERMINE ACCELERATION

  • Determine time of 1 part
  • Find initial velocity
  • Find final velocity
  • Total time = (Total parts - 1) x time of one part
  • ACCELERATION =v-u
  • t

...... . . . .. A B C D E F 2cm 8 cm 10. IMPORTANT!!!

  • *To find acceleration:
  • Total time = (Total parts - 1) x time of one part
  • *To find velocity:
  • Use a normal method without -1 !

11. TRY THIS!!

  • Find :
  • Acceleration
  • Average speed

. . . . 5 cm 7 cm 6 cm 12. TYPE OF MOTION

  • Distance between dot is same
  • Object moving with constant speed

. . . . . . . Direction of motion 13.

  • Distance between dot is increasing
  • Object moving faster / accelerate

. . ........ Direction of motion 14. 15. ........... . . Direction of motion The object is _____________________ 16.

  • The object is moving very _______________

. Direction of motion 17.

  • Ticker timer can be used to determine:
  • (State 4!)

18.

  • In the study of linear motion of a trolley on a runway; the time taken for the movement of the trolley is recorded by a ticker timer
  • TRUE OR FALSE?

19.

  • Vibrating steel strip will vibrate _________ times in a second

20.

  • Draw the diagram of ticker tape that shows the object is moving with decreasing velocity
