What was Galileo pendulum theory?
Galileo found that each pendulum has a constant period. The period is the time in which a pendulum completes a single oscillation, i.e., returns to the position it was in at the beginning of the period. For example: The time required for the pendulum to move from its most extreme right position back to that point.
What was Galileo’s pendulum experiment?
Galileo noted that lighter pendulums come to rest faster. As a test of this observation, two pendulums, nearly identical except for their bobs of different weights, were released at the same time and height. A bob of lead was hung with a string length of 28.9 cm. A bob of cork was hung to hang at 29.0 cm.
What is the period of a pendulum consisting?
A simple pendulum consists of a light string tied at one end to a pivot point and attached to a mass at the other end. The period of a pendulum is the time it takes the pendulum to make one full back-and-forth swing.
What is the period of oscillation on a pendulum?
each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.
What did Galileo’s telescope discover?
With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. His discoveries proved the Copernican system which states that the earth and other planets revolve around the sun.
What are Galileo’s astronomical observations?
Italian astronomer and physicist Galileo Galilei first used the telescope astronomically in 1609. He was the first to see such wonders as sunspots, which he described as blemishes on the Sun, and features on the Moon like Mare —seas or bodies of water. Galileo’s observations of the planets were monumental.
What is time period of pendulum?
The period of a pendulum is the time it takes the pendulum to make one full back-and-forth swing. A group of students are investigating the factors that might affect the period of a pendulum.
How do you find the period of a pendulum swing?
How to analyze a pendulum in swing
- Determine the length of the pendulum.
- Decide a value for the acceleration of gravity.
- Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s .
- Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz .
