Coin's motion under water Need Explanation

AI Thread Summary
The discussion centers on the mechanics of a coin's motion when dropped into a bucket of water, particularly focusing on the rotation and displacement of the coin as it enters the water. The primary factors influencing this behavior include the coin's shape, surface tension, and the interaction between the coin and the water. As the coin enters the water, it experiences forces that cause it to tumble and rotate, leading to unpredictable movement. The conversation seeks to understand the physics behind these dynamics. Understanding these principles can enhance gameplay strategies in the "Coin in a Bucket" game.

Homework Statement



There is time-pass game, "Coin in a Bucket".
In this game, we take a bucket full of water, and in the middle there is a small cup.
We are asked to put the coin in the small cup from above the bucket.

Now the point is, that whenever we place the coin from top of the bucket, it tumbles, rotates and gets displaced from the actual position.
I actually need to know what is responsible for this rotation and random movement of coin under water.?
 
Physics news on Phys.org
Edit: My initial post was probably too helpful.

Why do you think it tumbles?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
