Why does the bob come down by itself?
They do this for exercise and when they're happy, and it can also be part of breeding behavior. Head Bobbing Head bobbing can indicate that a bird is anxious to go somewhere, or perhaps he is regurgitating to you in an effort to bond with you. Very young parrots bob their heads a lot, as do quaker parrots.
How do you measure the period of a pendulum more accurately?
My physics textbook states that in measuring the time period of a pendulum it is advised to measure the time between consecutive passage though the mean position in the same direction. This results in better accuracy than measuring time between consecutive passage through an extreme position. Thereof, how long will a pendulum swing?
People also ask what happens if you swing the pendulum gently or swing it more forcefully?
Answer: When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. 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.
Why do pendulums make good time keeping devices?
The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. 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.)
What did Galileo discover about pendulums?
Galileo's discovery was that the period of swing of a pendulum is independent of its amplitude--the arc of the swing--the isochronism of the pendulum. [1] Now this discovery had important implications for the measurement of time intervals.
