Application of Aristotle with free fall

AI Thread Summary
Aristotle's theory suggests that the time for an object to fall is inversely proportional to its weight. In the given scenario, objects A (10g) and B (40g) were analyzed, with object B identified as having the highest terminal velocity. Terminal velocity occurs when the gravitational force equals the drag force (mg = Fdrag), but this detail is not essential for solving the problem. The discussion clarifies that Aristotle assumed objects fall at a constant speed, which is interpreted as terminal velocity in this context. Understanding the relationship between distance, time, and speed using kinematic equations can help derive the solution consistent with Aristotle's principles.

Homework Statement


Aristotle believed that the time it takes for an object to fall a given distance is inversely proportional to its weight. Given objects A,B,C and D with weights of 10,40,20 and 30 grams, which one would have the heights terminal velocity if dropped from the same height?


The Attempt at a Solution



I was done to object A (10g) and B (40g). The answer was object B.

My question is:

1)Terminal velocity is referred to when mg = Fdrag?

2) I see that time takes longer for object A than B, so how can I equate this to terminal velocity?

yes, but you don't really need this info in this problem.
2) I see that time takes longer for object A than B, so how can I equate this to terminal velocity?
Aristotle apparently presumed that the objects fall at some constant (uniform) speed, which the problem is referring to as 'terminal velocity'. You can use the basic kinematic equation that relates constant speed to distance and time to arrive at the 'Aristotlian' answer.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
