What does a pendulum look like?
People also ask is there a pendulum that never stops?
Even with an ideal bearing and no atmosphere, the light hitting your pendulum would eventually slow it and stop it. Perpetual motion is impossible. It won't happen. You can also ask who proved the earth rotates?
And another question, why does pendulum not stop?
If there were no friction or drag (air resistance), a pendulum would keep on moving forever. In reality, each swing sees friction and drag steal a bit more energy from the pendulum and it gradually comes to a halt. But even as it slows down, it keeps time. What force does not act on a pendulum? One force is gravity. The force of gravity acts in a downward direction and does work upon the pendulum bob. However, gravity is an internal force (or conservative force) and thus does not serve to change the total amount of mechanical energy of the bob. The other force acting upon the bob is the force of tension.
What is the law of length?
Law of length: The fundamental frequency of vibrations of a string is inversely proportional to the length of the vibrating string if tension and mass per unit length are constant. Is pendulum a periodic motion? The massive object is affectionately referred to as the pendulum bob. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, an example of periodic motion.
