Can you say yeah in the yes-no game?

The Yes Or No game rules are nice and simple. You ask a young person a long series of questions that would normally require that they answer "Yes" or "No"; however, the young person isn't allowed to say either of these words. They're also not allowed to nod or shake their head.

Who discovered pendulum clock?

Christiaan Huygens Pendulum clock / Inventor. Being bedridden is never much fun, but sometimes it can lead to scientific insight. Such was the case with 17th century Dutch astronomer Christiaan Huygens. Subsequently, does a pendulum ever stop? A pendulum can only stop when its gravitational potential is lowest and it no longer has energy driving it. (This is of course assuming the pendulum is allowed to swing until brought to a stop by friction, rather than being stopped by an applied force.)

Moreover, how long will a pendulum swing?

And another question, why is the pendulum important? It states that a body at rest, stays at rest and a body in motion stays in motion, unless acted on by an outside force. Pendulums provide proof of Newton's first law of motion.

Regarding this, what are the forces acting on a pendulum?

The forces acting on the bob of a pendulum are its weight and the tension of the string. It is useful to analyze the pendulum in the radial/tangential coordinate system. The tension lies completely in the radial direction and the weight must be broken into components. What happens if you just let the bob swing back and forth? When you let go of the raised bob, its potential energy is converted to kinetic energy as it swings down with increasing speed, and then back to potential energy as it swings up on the other side with decreasing speed.

How do you test a pendulum with food?

Observe which way the pendulum moves. If it moves in the 'yes' direction, your body holds resonance with the food being tested. If it moves in the 'no' direction, your body does not hold resonance with the food and cannot fully assimilate/metabolise the food.
