Simple physics experiment (The conservation of energy)

This video shows another way of conservation of energy.

Can I ask about the manipulated and responding variable in this experiment? Looking forward for your reply.

This is great. How would you explain the gradual decrease in the overall system over time... is this due to friction?

Does anyone knows what are dependent and independent variables here? I need it for my lab report :(((

Interesting, so does that somehow prove that people can transmute energy between each other? So if someone feels bad or in a good mood, you can pick that up? a vibe so to speak?

Try some new solutions from Avasva solutions.
