AI Thread Summary
Vorticity plays a significant role in the rolling motion of soup cans, particularly in how different types of soup affect their movement down a slope. The cream soup can roll further than the consomme at steeper angles due to differences in fluid dynamics and energy transfer within the cans. The discussion highlights the importance of understanding energy impartation and the internal behavior of the fluids in relation to their viscosity. Additionally, there is interest in developing mathematical models to analyze these effects, potentially using software like Maple or Matlab. Overall, the interaction between fluid properties and rolling dynamics is crucial for predicting the behavior of the cans.

Hi,

I was thinking the other day of two soup cans of different types(one cream one consomee) rolling down a slope. I was thinking that the non-cream one (consomee) will always roll longer, but was surprised to find out that past a certain angle the cream soup was going longer. By longer I mean the distance from the end of the slope.

So I did a bit of research and I found out about vorticity, and that's about it. But what I was really wondering is how is the energy imparted in these cans, and what is going on in there. Also why exactly did the cream one roll further for high angles?

To give you an idea of my level of Physics, I did take an AP Calculus course and I am currently taking AP Physics, so I can understand harder math and some vector calculus. The reason I posted this question in Advanced Physics is because of the AP courses which are more or less like first year courses.

Thanks,
Alex

PS:Is there some kind of Mathematical Model for Maple or Matlab? OR even just a mathematical model by itself?

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
