Wow, this is the video that finally allowed me to understand how the pendulum could just keep swinging. It's being pushed back. I finally understand why you have to rewind the weights.
same principle as the pocket/wrist watch, only there the pendulum is driven by the "hair spring" instead of gravity, and there's also the main spring instead of the weights
@@gundabalfin a watch the part of gravity here is played by the main spring. The hair spring is more like the oscillation of the pendulum. I only recently realised that watches are backwards to how I thought. They’re not driven by the pendulum. But regulated by it.
The hanging load is wound around a large gear and provides the energy in the system. The pendulum regulates how much energy can be released since the main gear can only move when the pendulum swings to the left.
Hello… Galileo has nothing to do with the invention of the pendulum clock. He only described and proved that swinging time has nothing to do with the weight of the pendulum but it’s the length that got the most effect…. On dec 25 1656 Christiaan Huygens made the first working clock due to this principle and become the official inventor of the pendulum clock. Galileo died almost 9 years earlier on jan 8 1642.
the gravity is free but once the object reaches the ground there is no more gravity and so to utilise the gravity again you still need energy to pull the object up from the ground.
