The first thing we did was take the video and use tracker and make spreadsheet and put every thing on a blogger, and on tracker we found the movement of the object to find, distance and displacement and to tell how far it moved in one place.
The video you see here is used to show the purpose movement in the object.
see the movement to the measure the time and distance.
Then use the of the distance formula and find meter/seconds
To find your data.
There not any big errors, but every time you moved the frame the bug itself would move as whole.
I learned that when an object is motion then you stop and take a place some where else move much greater distance.

An example when I drive to school at 70m/h and it take 4mins and the distance is 8mile
so at 70m/h every 2 mins I go 2miles so it take 4 mins to 8 miles,
