Center of gravity and Newton's 3 Law of Motion.

AI Thread Summary
The discussion focuses on a project demonstrating a physics phenomenon related to Newton's Laws of Motion, specifically the center of gravity. The participant plans to use an empty can filled with water and then smashed ice to illustrate circular motion. There is confusion about how the third law, which states that every action has an equal and opposite reaction, is demonstrated in this setup. The effectiveness of the demonstration in showcasing Newton's laws is questioned, particularly regarding the third law's application. Clarifying the connection between the demonstration and the laws of motion is essential for the project.

I have a project to do and I have to make a demonstration about a physics phenomenon. I'n planning on doing a demonstration that explains one or all of Newton's Laws of Motion. I've chosen to do it on the center of gravity, but I want to know if it's
related to Newton's 3 Laws of Motion or is it not?

third law is "every action has an equal and opposite reaction"

so some demonstrations may work and some may not

whats in your mind?
 
Well in my demonstration, I'm planning on taking an empty can and filling it with 1/3 of water to make it rotate in a circular motion on its edge. After I'm going to fill it with smashed ice instead of water and do the same thing.
 
Ok, I am a bit confused ... how is 3rd law demonstrated in it?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
