Coin's motion under water Need Explanation

Click For Summary
SUMMARY

The discussion centers on the physics of a coin's motion when dropped into water, specifically in the context of the game "Coin in a Bucket." The primary factors influencing the coin's tumbling and random movement include water resistance, surface tension, and the initial angle of entry. The interaction between the coin's shape and the water's viscosity contributes to its rotational dynamics and displacement from the intended target.

PREREQUISITES
  • Basic understanding of fluid dynamics
  • Knowledge of surface tension principles
  • Familiarity with rotational motion concepts
  • Experience with experimental physics methods
NEXT STEPS
  • Research fluid dynamics and its effects on solid objects
  • Study the principles of surface tension and its impact on object behavior in liquids
  • Explore rotational motion and angular momentum in physics
  • Conduct experiments on object displacement in various fluids
USEFUL FOR

Students studying physics, educators teaching fluid dynamics, and hobbyists interested in experimental physics related to motion in liquids.

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?
