2D motion analysis

video

Work for problem:

a = 9.8m/s^2
Change in vertical direction = .87m
t = ?

delta y = t + 1/2(a)^2(t)^2
.87m = 1/2 (9.8)^2(t)^2
.87m = 4.9(t)^2
.174 = t^2
.42s=t

We repeatedly calculated the measurements for the precise length from the table to the ground. When we measured the height of the table it came out that when we rolled the ball it hit the ruler. When could use this to balance the wings on an airplane.

bug chart

Procedure
     1. Set up a box for the bug with a grid in the bottom.
     2. Record the bug in the box for about 30 to 45 seconds.
     3. Watch the video and -pick out an interesting section about 10 seconds long.
     4. Get the bugs position and watch the video frame by frame stopping occasionally to write down the frame number and bugs position.
     5. Finally put all of the data in a spreadsheet.

Conclusions: I learned that distance and displacement are two totally different things. I found that this principal can be applied in driving. If you leave a parking lot and come back to the same parking spot your displacement is 0 but your distance isn't.
