speed distance time experiment

Aim:
I want to investigate the relationship between distance and time and speed and time.


equipment :
.  pole with 3.18m string attached
. person moving around the circle
. stopwatch
. paper and pen to write results

method
.first we put together our 20 m circle outside
. we set up our person and stopwatch
.    start timing person  3 laps, walking, jog then running
.       get results
.          draw a distance time graph




results :

time (s)	distance (m)
0	0
14	20
24	40
31	60
36	60

lap number	distance (m)	time	laptime	speed
start	0	0	0	0
lap1	20	14	14	1.42
lap2	40	24	10	1.6
lap3	60	31	7	1.93
finish	60	36	5	1.71

Discussion 

  

Is there a relationship between speed distance and time?

yes there is because distance travelled   ,time taken  and speed is how far  you went.

The change in speed is acceleration 

Evolution

This speed time graph is wrong because the lines look like its  constant acceleration each time it goes up.

In the experiment ,it only took a few steps before moving/acceleration.

This is what its supposed to look like:
