    Drop Graph
Click For Summary
The experiment investigates the relationship between the time it takes for dominos to fall and the distance between them. It is suggested that the graph should not include a point at the y-axis since a distance of zero would not yield meaningful results. Instead, starting with a minimum distance, such as 2 centimeters, is recommended for accurate data collection. The proposed graph would plot time taken against the number of fallen dominos, resembling a cumulative distribution function. This approach aims to clarify the correlation between distance and fall time in the experiment.

Homework Statement


I'm doing an experiment on the relationship between the time it takes for a line of dominos to drop and the constant distance between each domino. I plan to try different distances to get different times, but I don't know what my graph should look like, nor do I know if a point should be placed on the y-axis, since you can't really have 0 distance between the dominos and expect accurate results. If someone could give me some pointers on what a graph should look like in this instance, that'd be great.


Homework Equations


Not sure if I need any.


The Attempt at a Solution


Judging by the fact that you can't really expect the dominos to drop if there's no distance between them (as it'd be one packed line) I assume that I just shouldn't put a point on the y-axis and should, instead, start my experiement with 2 centimeters displacement between each domino or so. When I make my graph, I'd have a line segment beginning at that point instead of having it start when x=0.

Well if you plot the time taken vs the number of dominos fallen, then I think you'll essentially be plotting a sort of cumulative distribution function type graph.
 
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?
