Newton's Law Project

Students will be posting their video/movies explaining how Newton's Laws of Motion apply to an activity of their choice on their own blog. The above video was taken with an iphone.  I am posting it here from a PC to determine if students will be able to do this from their devices. The above is raw footage below is a "movie" put together using video clips in Movie Maker. 

I have run into a problem uploading the Movie Maker movie here.  I cannot get the up-loader to allow me to choose the video?  hmmm. Even after waiting several minutes it doesn't open.  After publishing and returning to edit, the up-loader is now working.  Go figure.

Now, after publishing the movie will not play.  Why does this stuff have to be so frustrating?  Now trying uploading to YouTube and then uploading to this post.

Investigations and Experiments

Seventh period data. First column of numbers is the trial with the photogates set at 5 cm and 80 cm. Second set is with the gates 10 cm apart disregarding location on the ramp. In two or three sentences describe why the data in your first trial was more reliable than in the second trial.Your answer should talk about variables.

8th period data. First column data is when you had the photogates 10 cm apart and the ramps are at various heights.  The second column is when the ramps were at different heights but the gates were all 75 cm apart. In two or three sentences describe why the data in your second trial was more reliable than in the first.  Your answer should talk about variables.

First period data is to the left.  The first column numbers are the ones with 10 cm intervals with no attention to location of the gates.  The second column of data is acquired with the gates 75 cm apart and all groups' gates at the same location.  Two groups gave their car a nudge and caused "bad" data. Answer the following: In two or three sentences describe why the data in your first trial was more reliable than in the second trial.Your answer should talk about variables.
