r = 0.09m 



r = 0.12m



r = 0.15m 



r = 0.18m 




Velocity formula

Data values

Graph of Velocity vs Radius and Acceleration vs Radius:

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

Yes the velocity vector was moving in the expected direction using the velocity components. 

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 slope of this graph represents the angular velocity.


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 slope of this graph represents the angular acceleration.


Conclusion:

How do your results compare to your predictions?

We predicted the velocity v radius graph to be a linear graph which adds up and the acceleration v radius graph to be constant and positive values which also lines up correctly so I would say our predictions did match up in comparison to our results.

Coefficient of Kinetic Friction Lab

  1. For each new block mass, calculate the magnitude of the kinetic frictional force from the measured t.  Also determine the normal force on the block. 2. Graph the magnitude of the kinetic frictional force against the magnitude of the normal force, for a constant angle of incline.  On the same graph, show your predicted relationship. 3. For each angle (h), calculate the magnitude of the kinetic frictional force from the measured t.  Also determine the normal force on the block. 4. Graph the magnitude of the kinetic frictional force against the magnitude of the normal force for a constant block mass.  On the same graph, show your predicted relationship. 5. Calculate the uncertainty in your experimental technique.   Do your two graphs agree? My two graphs do not agree, i don't know what happened with the second graph Conclusion:  What is the coefficient of kinetic friction for wood on aluminum?  How does this compare to y...

angular velocity lab

 Analysis Determine the final angular velocity of the ring/disk/shaft/spool system for each case after the weight hits the ground. How is this angular velocity related to the final velocity of the hanging weight?  Be sure to use an analysis technique that makes the most efficient use of your data and your time.  If your calculation incorporates any assumptions, make sure you justify these assumptions based on data that you have analyzed.   Conclusion In each case, how do your measured and predicted values for the final angular velocity of the system compare? They compare pretty well with 2 of them matching and trial 2 or pulley 2 being slightly off from the predicted value.  Of the three places you attached the string, which produced the highest final angular velocity?  Did your measurements agree with your initial prediction?  Why or why not?  What are the limitations on the accuracy of your measurements? Trial 1 which was the largest pulley prod...

Individual contributions to project 2

Designing and creating the cart used in our presentation using materials scavenged at home.  helped organize the slides by inputting images of our computational graphs along with pictures of the cart and a video of both the cart and computational model running. Also helped with writing our goals and how we designed the cart slide. Put in photos of our labs we did into the presentation that were used to calculate values and towards creating the cart.  Stayed communicative with my group by creating our own discord group!  Provided a video of the cart to help create the computational model of our cart.
