Science: Forces & Motion - Speeding Past School

Speeding Past School Experiment 

Aim: To see how many cars are speeding past the school.

Method:

1) Measure the distance of power pole to power pole = 50m

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

3) Collect 10 times.

4) Calculate speed in m/s then covert it to km/hr.

5) Are there any speeders?

Roles:

- "Flag" The person indicates when the car passes their pole. 

-  "Timer" The person starts when the car stops and when the car passes their pole.  

- "Writer" The person writes down the time speeds.

Results:

Speed	Car 1	Car 2	Car 3	car 4	Car 5	car 6	car 7	car 8	Car 9	Car 10	Average
Time	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	47.35	34.812	57.492	36.72	53.712	43.056	40.38

Conclusion:

In conclusion in this experiment, the results are all different. Some cars are in the line of 30 to 50 and some others are past the limit of 50 km/hr but only by a few seconds. The average speed according to our experiment was 40.36 km/hr.
