Very nice. I think everyone can appreciate the effort you put into this. IMHO, it's always good to mention the starting location in your formula (X at t=0), even though it's value is 0. Just like you put in a starting velocity of 0. This helps people later as the velocity is derived from the location, and the acceleration is derived from the velocity. Keep up the good work! Hope you got an A!

OK ... for your next demonstration ...
... try it with a hammer and a feather ...
... on the moon!!

yay Americans!!!

@BladePenguin velocity is a vector, a negative velocity points in the opposite direction to the reference direction for a single dimensional problem
ie if left to right is the reference direction, right to left becomes negative.
and it is not distance (a scalar), it is displacement (a vector), where a scalar 'value', tells you the magnitude and the vector gives the magnitude and direction.
eg vel. -5m/s gives a 'scalar speed' magnitude of 5, and a direction of right to left wrt our ref.

deltaV = 0.5a (delta t)^2 not a^2, its t^2 where delta x = xfinal - xinitial.

what was your procedure? :)

@lindseybaby138 Um, in all honesty we just kind of put it together as we went along. We made huge flash cards so we could read off of them and used some examples out of our textbooks. :)

Nice job girls. Let ma ask you, did you guys do this for a final project? I have been having my students do videos like these as final projects for a few years, but am looking for more videos to mirror for them as examples and I think yours was great! Would you mind if I downloaded it to use as an example? and if so, did any of your classmates do similar ones?

@odinsraven1000
I'm so sorry that I haven't responded to this. But sure go ahead and download it :)
Everyone in my class did a different subject that we were assigned. Most of them aren't on youtube though. But I think that the videos helped out a lot before the regents.

how can the final velocity and distance be negative?

@BladePenguin
It was showing direction.
