Science: Speeding Past School

Hi, Today in Science we are conducting an experiment regarding the speed of cars travelling past the school.

Aim: See how many cars are speeding past school

Method: 

1) Measure distance... power pole --> power pole = 50m

2) Time how long it takes a car to travel this distance 

    - "Flag" person indicates when a car passes their pole

    - "Timer" person starts when ⮥ & stops when a car passes their pole
    - "Writer" person writes downtimes
3) Collect 10 times
4) Calculate speed in m/s --> convert to km/hr 

5) Are there any speeders?

Results: 

Speed	Car 1	Car 2	Car 3	Car 4	Car 5	Car 6	Car 7	Car 8	Car 9	Car 10	Average
Time (s)	4.84	3.80	5.57	5.83	3.80	5.17	3.13	4.90	3.35	4.18	4.457
m/s-1	10.33	13.15	8.97	8.57	13.15	9.67	15.97	10.20	14.92	11.96	11.21
Km/hr-1	37.188	47.34	32.292	30.852	47.34	34.812	57.492	36.72	53.712	43.056	40.36

Conclusion: 

According to the results, none of the cars really passed the average standard speed of 50km/hr on the road. The average speed according to our experiment was 40.36 km/hr.
