# Uniform Circular Motion

1. The problem statement, all variables and given/known data
I've done an experiment on uniform circular motion. Pretty much, there is a hollow tube and a strong goes through it. One one end is a stopper and on the other is a weight. I had to spin the stopper side, buy keeping hold of the hollow tube, keeping the string at a constant rotation.

I have to explain how this experiment illustrates all three of Newton's laws of motion.

2. Relevant equations
N/A

3. The attempt at a solution

First law: The stopper doesn't stay in motion when there is no force exerted on the spinning because of the weight on the other side.
Second law: The force is based on the mass of the stopper and the acceleration exerted by spinning.
Third law: Not too sure...

Could someone please correct me if I'm wrong and provide their insight on all three laws?
Thank you, the help is very much appreciated.
