I don't know why my teachers couldn't make it so interesting at high school. Thanks a lot for the video.

G Yogaraja Teaching is a skill.

Probably the best channel on youtube, thank you Sir.

What a great video The demonstrations were very easy for me to follow. Thank you

An excellent introductory to differential equations problem (using small angle approximations)

This guy gives the excellent and the best explanation, I wish all teachers around the world can explain like this wonderful teacher. His voice is very effective and attracting, his way of teaching is the best of best, thank you very much sir for all your awesome lectures, we will love you always,

another excellent video, thanks.

great video well done!

very nice, thank you

Very interesting and informative! Thank you for sharing in 2014. Happy New Year in 2015.

thanks for the help and cool planes

that was an amazing video

Brilliant explanation 👍😊💛...

Good teacher.

Thank you

Thanks this was very helpful

You can also use it to determine the value of pi if you know the length and the gravitational acceleration in your neighborhood

No, this can't be accomplished, because, well you can always take the same length anywhere you are on earth, but gravity is different at different locations on earth. This will give you different values of pi everytime, which is against the definition of pi (A Universal Constant). No matter where you are in the Universe trying to measure/calculate pi, and no matter what experiment and techniques/Mathematics you use to find pi, you always end up getting the same result. That's why, pi is called The Universal Constant.

Brilliant

Very interesting.

To make a pendulum period really independent of amplitude, one can add a pair of cycloid plates up near the pivot. Can you demonstrate and explain this? What errors in the pendulum equation does this reduce? What size cycloid plates are best for a pendulum of a given length?

This is gold

Kepler's third law says T^2 = A^3, this also means T = A^1/2. it is very similar to Pendulum equation.

back in 2300 BC people know about *second pendulum *🙂

How about that Goldberg Cub on floats?

What about the pit?

Thanks! Well done! Very interesting. Now, we need to get the "right" people to view it!!! LOL

Don't we need to take air resistance into consideration?

If the setup is identical over the same number of swings then the influence is also consistent. There will be an insignificant change as atmospheric pressure changes just as the boiling point of water changes with atmospheric pressure. Obviously if you attempted the same experiment with (say) 100 swings then the results would become skewed as the pendulum slowed down. You could however try 10 individual runs of 10 swings each.

It has nothing to do with gravity! Because there is no such a thing as one.
