Equation for time period of a pendulum :- T = 2*pi*√(length/g) Or T is directly proportional to length of string Which means longer the string higher the time period and lower the velocity. I hope this explains something....❤️

🔴 What Is Islam? ⚠️ 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

[@themarquis336]

What’s most extraordinary about this is that, minus air currents that may affect it, none of it is random; every second of it is calculable and predictable.

[@andrewwebb4635]

What a fantastic video! I particularly like the moment when the seemingly chaotic action comes back almost to the exact starting point and it all starts off again. This is surely the ‘strange attractor’ of chaos theory shown so clearly in action? It’s very interesting that out of chaos comes order just as much as the more familiar human experience that out of order comes chaos

[@ericy1817]

This isn't chaos theory at all, nor is the motion actually chaotic in the mathematical sense. And you guessed it, this has almost nothing to do with strange attractors.

[@kenmunozatmmrrailroad6853]

[@drumkommandr9779]

Fun fact: right at the end, there, where they almost line back up. Measuring the offset between them at the moment they're most aligned will give you a precise cumulative measurement of the energy losses in the system due to things like gravity, friction, and drag.

[@anmol348]

*Everything depends upon the time period which is = 2π √l/√g* Here l is length of pendulum ..if l increase time period too increase and frequency decrease ....which means number of oscillation will be less in *greater length of golf ball from support* So T=2π * √l/√g And T is indirectly proportional to f Where T is *time period* f is *frequency*

[@Night_Hawk_475]

I wonder if the colored golf balls and the white ('normal') golf balls have different masses? At the very end there when they were supposed to line up it seemed like they were "out of synch" based on whether they were white or not. All the white ones were just a little behind (or ahead, idr which, just all off about the same amount) I know mass doesn't factor into the pendulum period equation, but it would matter for air resistance purposes, as objects with more mass would preserve more momentum over time.

[@donfletcher2348]

It puts me in mind of fractal geometry in the way the same pattern repeats on a smaller scale.

[@robertreynolds1044]

I think that the added paint may have affected the movement because of the synchronicity when the white/ colored seem to pair up near the end, where they should still be evenly spaced. My name is Bicycle Bob and I approved this message.

This reminds me of planets orbiting the sun. The ones with less distance from the sun revolve more quickly, and those furthest away orbit very slowly. But periodically there are 'resonances' where they line up. Quite often between the inner planets, but now and again they all fall in line. It's contributes to the stability of the system, and is also hypothesised to be the reason that the Asteroid belt is unable to coalesce into a planet, because of the gravitational resonance between Mars and Jupiter.
