How did the pendulum clock affect society?
The introduction of the pendulum, the first harmonic oscillator used in timekeeping, increased the accuracy of clocks enormously, from about 15 minutes per day to 15 seconds per day leading to their rapid spread as existing ‘verge and foliot’ clocks were retrofitted with pendulums.
What are the uses of pendulum?

Why is pendulum important?
Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.
What is pendulum energy?
An ideal pendulum system always contains a stable amount of mechanical energy, that is, the total of kinetic plus potential energy. As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy.
Why do pendulums stop swinging?
The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. A clock is “in beat” when the tick and the tock are evenly spaced.
Who moves the pendulum?
Where Do the Answers Come from? There is no power in the pendulum itself; this is important to remember. It is you who has the power, and you who has access to all of the information and answers that you seek. The pendulum is merely a tool (albeit a powerful and useful one) to help you discover those answers.
What does the pendulum symbolize?
The most obvious symbol is that of the pendulum. It descends from an image of Father Time—himself an age-old symbol of the passage of time—who usually carries a scythe, a symbol of harvest and therefore of the end of the cycle of growth in the life of a plant.
Can you pendulum summon from the graveyard?
Whenever one of your Pendulum Monster Cards on the field (regardless of which Zone it is in, or even if it is a monster or not) would be sent to the Graveyard, place it face-up on your Extra Deck instead. You can Pendulum Summon it back to the field later!
Can you negate pendulum summon?
A Pendulum Summon is a type of built-in Special Summon, so it can be negated by cards like “Solemn Warning” and “Thunder King Rai-Oh”; however, if more than 1 monster would be Pendulum Summoned at the same time, cards like “Black Horn of Heaven” (which specify they can only be activated when exactly 1 monster would be …
How do you destroy a pendulum monster?
Pendulum Monster Cards Can’t Be Completely Destroyed Whenever a Pendulum Monster in one of your Monster Card Zones, or a Pendulum Spell Card in one of your Pendulum Zones would be sent to the Graveyard, no matter what the reason, it’s placed face-up in your Extra Deck instead of in the Graveyard.
Can pendulum monsters attack from the pendulum zone?
These monsters can be Fusion, Synchro or Xyz Summoned (depending on their monster card type) as normal while face-down. Because they are Extra Deck monsters, they cannot be activated to the Pendulum Zone from the hand.
