Motion Lab
Purpose
This lab will help give us a better understanding of velocity by graphing a story with a constant positive, variable positive, and variable negative velocities, and a
velocity of zero, or a constant position.
velocity of zero, or a constant position.
The Story:
A rocket is motionless on a platform, and then it was fired with a slow velocity to start with that gradually increased. After about a total of five minutes the rocket has reached it's maximum velocity and with remain at that velocity for another two minutes. Finally, the rocket will lose it's momentum and fuel, so then it starts to drop, slowly at first then more rapidly as it approaches the ground.

Equipment
You will use: a couple sheets of paper, a motion sensor, and a LabPro
Procedure
First, try to sketch the graph you are anticipating, ours is at the top of this page.
Then, set up the motion sensor so that you will have plenty of room to move.
After that, you should try and act out your story so that the position graph on the LabPro resembles your sketch.

Data
Here is the graph we created using the motion sensor and the LabPro. Because we could not move 3000km away, nor could we do it for 8 minutes, we scaled the graph so that the position is actually in terms of 1000 Km not meters. Also the time is scaled for minutes rather than second. We couldn't change the scale when we put the graph on a document. Lastly, ignore the wild part that comes after the 8-8.3 minute mark, because out data had ended.

Conclusion
In conclusion, we managed to come up with a story that includes the required velocities, and we produced an accurate sketch of the rocket's movement, and we created a similar graph using the motion sensor and LabPro. We had some difficulty creating the similar graph, but eventually we got one that somewhat resembles our sketch.
