When the pendulum is still, ask the question “What is yes?” The pendulum will begin to move, and this indicates what the answer “Yes” looks like. It may begin to swing clockwise or counterclockwise, or it may move from side to side or back and forth.
How do pendulums work?
When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.
Does a pendulum answer questions?
“You can use the pendulum to help you with any problem, troubling situation, or something you need more clarity around.” Just remember: The pendulum can only answer “yes” or “no” questions. “So make sure to phrase questions in a way that can allow you to get a clear answer,” she says.
What does it mean when the pendulum swings back and forth?
This back and forth motion is called “oscillation.” Its position is said to oscillate back and forth. The period is the amount of time it takes the bob to make one round trip. If the pendulum bob is pulled back and released, it returns to the hand that released it after a time interval equal to one period.
How do you tell if a pendulum says yes or no? – Related Questions
Why does a swinging pendulum come to rest?
A pendulum is a simple example of energy transfer – converting potential energy to kinetic energy over and over until the small amount of energy lost to heat and air resistance causes the pendulum to come to rest.
What causes a pendulum to change direction?
The Earth moves around it. A pendulum swings only due to the forces of gravity, inertia, and air resistance. Even the rotation of the Earth does not change its motion.
What energy does a pendulum lose?
The pendulum loses energy to wind resistance, friction between the tube and the string, and internal friction within the bending string. When the driver is pumping energy in, the amplitude of the pendulum increases, along with the frictional losses.
Do pendulums move on their own?
Hand-held pendulums can seemingly oscillate on their own, without perceived conscious control. This phenomenon, known as the Chevreul pendulum illusion, is likely a result of subtle muscle movements caused by thinking of the generated movement.
What affects a pendulum the most?
The only factor that significantly affects the swing of a pendulum on Earth is the length of its string. Students might wonder why the length of the string is the only thing that affects a pendulum’s period.
Does pendulum swing or drift back and forth?
A pendulum is a mass (called a bob) that hangs from the end of a rod or string, and swings back and forth.
What is the meaning of swinging pendulum?
: a body suspended from a fixed point so as to swing freely to and fro under the action of gravity and commonly used to regulate movements (as of clockwork) : something (such as a state of affairs) that alternates between opposites. doesn’t take much to swing the pendulum of opinion the other way.
What is the swinging pendulum theory?
In politics, the Pendulum Theory states that popular mood swings to one direction, until it reaches its periodic limit, and then it is inevitable that it swings back to the other side.

The pendulum loses energy to wind resistance, friction between the tube and the string, and internal friction within the bending string. When the driver is pumping energy in, the amplitude of the pendulum increases, along with the frictional losses.
What stops a pendulum?
The pendulum stops eventually because of air resistance. The pendulum loses energy because of friction. Only in a theoretical situation when there is no friction the pendulum will oscillate forever.
Where does the energy go when a pendulum stops?
With less kinetic energy, the swing slows down. When all of its mechanical energy has been converted to thermal energy, the swing stops. It no longer has potential energy or kinetic energy. But the total energy in the system remains the same.
Does a pendulum go forever?
No pendulum can swing forever because the system loses energy on account of friction. That’s why a grandfather clock has to be rewound every few days, to inject a little energy back into the system.
