Do pendulums swing forever?

Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. No pendulum can swing forever because the system loses energy on account of friction.

Thereof, why does my pendulum wall clock keep stopping?

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. Regarding this, why pendulum stops after some time? The pendulum bob stops oscillating after sometime due to the air resistance offered to it and due to the friction at the point of support.

What law does a pendulum follow?

Physicists use Newton's first, second and third laws to prove the horizontal string tension moves the pendulum without regard to mass or gravity. The laws of a simple pendulum follow the ideas of Newton's three laws of motion. What is the purpose of a pendulum lab? The purpose of this lab is to prove mass has no affect on the period of a pendulum only the length of the pendulum affects the period of the pendulum.

And another question, who discovered the law of pendulum?

Such was the case with 17th century Dutch astronomer Christiaan Huygens. He became the first to report the phenomenon of coupled oscillation in two pendulum clocks (which he invented) in his bedroom while recovering from an illness in 1665. Moreover, how do i not influence my pendulum? Tips for Successful Pendulum Use Always specify the source before asking questions. Cleanse the energy around and within you. Quiet your mind (both before and while using your pendulum). Breathe. Ground yourself. Be present - Do not multi-task. Be patient. Be objective.
