Conservation of Energy - Best demonstration Ever !!

Professor walter lewin demonstrates the law of conservation of energy using a swinging pendulum bob.
If the pendulum is released with zero speed, it can never rise above the initial point of release since that would imply free energy.

Nice experiment by the physics teacher

[jatinsatyam]

I hope your channel get more attention you give us so good learning videos that we are unable to get even after paying money to teachers here in India, Mumbai
Mumbai us not a great city
It is 80 percent worst city for education and 20 percent is nice

Two balls won against one.
Just my theory....

The energy is reduced or it is constant.

It's really old video, someone just uploaded it again so not many comments

[ranjeetpatel]

So good experiment but here is no any comment at this
Thats not good
A teacher who learn you something by writing
And a teacher who is teaching you by experiment the
Why ???

[girishkuvalekar]

It's because it was allowed to freefall

[gowtham]

Ok good.
But it is about conservation of energy aa ? 🙄🤔
