Constant acceleration from X vs. T on logger pro

Click For Summary
SUMMARY

The discussion centers on using Logger Pro to analyze motion data for an object moving with constant acceleration. To determine acceleration from a position vs. time graph, one must calculate the change in the slope of the tangent line, as the slope represents velocity. The user initially confused the slope with acceleration but later recognized the need to assess the change in slope to derive acceleration. Logger Pro 3 is mentioned as a tool, although the user has limited access to its features.

PREREQUISITES
  • Understanding of position vs. time graphs

Homework Statement


I have a conceptual problem that involves logger pro. Unfortunately, I do not have access to logger pro. Here it is: Suppose you have used a motion detector to collect data for an object that is moving with constant acceleration. Describe how to use LoggerPro to determine the value of the acceleration of the object from a position vs. time graph


Homework Equations


None


The Attempt at a Solution



I believe you just take the slope of the tangent line at a point on a position vs. time graph to find the acceleration at that point. I'm not confident in my answer because I do not reference loggerpro at all. Is there another or more correct way. I downloaded the loggerpro 3 demo but I have limited access and cannot graph motion with constant acceleration without sensors. Any help would be appreciated. Perhaps there is a slope of the tangent line function in the software?

Would that not give the velocity rather than the acceleration?
 
Yes it would. I realized that I made that error after I left the computer. So, I'm guessing you could calculate the change of the slope of the tangent line.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
