Rotational Kinematics

Analysis:

radius = 0.05 m

radius = 0.10 m

radius = 0.15 m

1. Use the velocity components to determine the direction of the velocity vector. Is it in the expected direction?

    Yes, the velocity vector was in the expected direction. We spun the bar clockwise and it shows.

2. Analyze enough different points in the same video to make a graph of speed of a point as a function of distance from the axis of rotation. What quantity does the slope of this graph represent?

    The angular velocity is represented by the slope of the graph.

3.  Calculate the acceleration of each point and graph the acceleration as a function of the distance from the axis of rotation. What quantity does the slope of this graph represent?

    The angular acceleration is represented by the slope of the graph.

CONCLUSION: How do your results compare to your predictions?

My prediction was that the acceleration vs radius graph would show a constant acceleration in the positive direction. 
The velocity vs radius graph showed that they are linear in the positive direction. 
My prediction was incorrect, but it makes sense since they are all parallel and going the same acceleration. 

Project 2 Individual Contributions

1. I printed and was the "mechanic" of the cart. I did most of the work involving the vehicle (testing, constructing, designing, CAD, budget).

2. I created and designed half of the slide show. 

3. I communicated a lot with group in regards of maintaining a timeline. 

4.  Assisted where I could with the computational model (a little help).

5. I did most of the analysis of the cart (video analysis). 

6. Organized meeting times with Julie to work on the project.

Thoughts: I enjoyed the project. The manufacturing of the cart and its parts was great. The labs and other parts for this project felt rushed.
