Galileo discovered that the time a pendulum takes to swing to and fro through small distances depends on only the length of the pendulum . the time of a to-and-fro swing, called the period, does not depend on either the mass of the pendulum or the size of the arc through which it swings.
What is the time for a complete to and fro swing of a pendulum?
The times for a complete to-and-fro swing of a pendulum is called its frequency . The number of times a wave vibrates each second is called its period. You just studied 13 terms!
What happens to the period of a pendulum as its frequency is increased?
Shorter pendulum give a shorter period (i.e. less time for an oscillation) and therefore more cycles per second or a bigger frequency. ... Frequency decreases the period increases .
Does the period of a pendulum depend on the mass of the bob on the length of the string quizlet?
Does the period of a pendulum depend on the mass of the bob? ... The period does not depend on the mass , but on the length of a string. A grandfather pendulum clock keeps a perfect time.
What is meant by the period of a pendulum quizlet?
What is meant by the period of a pendulum? the time a pendulum takes to swing to-and-fro . ... Period is the time from one crest to the next, amplitude is the distance from the midpoint to a crest, wavelength is the distance from one crest to the next, and frequency is the number of crests that pass per second.
What are the factors that affect the frequency of a pendulum?
Explanation: The only two factors that affect a pendulum’s frequency are the acceleration due to gravity (g) and the length of the pendulum’s string (L).
Does the mass of a pendulum affect its period?
The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.
What causes a pendulum to slow down and stop swinging?
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.
How do you tell if a pendulum is saying yes or no?
Here’s an example of how to program the “yes” signal: Holding the pendulum in position, say “When I ask a question and the answer is yes, move like this, in a clockwise circle .” (or whatever signal you’ve chose for “yes”).
Which pendulum will swing faster?
Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right.
What happens to the period if you double the frequency of a vibrating object?
If the frequency of the wave is doubled, the period becomes halved .
What happens to the period as the length of the string decreases?
The length of the string affects the pendulum’s period such that the longer the length of the string, the longer the pendulum’s period. ... A pendulum with a longer string has a lower frequency, meaning it swings back and forth less times in a given amount of time than a pendulum with a shorter string length.
What is the period of a pendulum that takes 1 second to make a complete back and forth vibration?
what is the period of a pendulum that takes one second to make a complete back-and-forth vibration? Suppose that a pendulum has a period of 1.5 seconds. How long does it take to make a complete back-and-forth vibration? The period of the pendulum would be 1.5 seconds divided by 1 cycle = 1.5 seconds .
What is meant by the period of a pendulum group of answer choices?
The period of a pendulum is the amount of time required for the pendulum to complete one full back-and-forth motion – from its rightmost point back to its rightmost point again, for example. The time required to swing from its rightmost point to its leftmost point is half of a period.
What 3 variables were changed in the pendulum experiment?
3 The three pendulum variables
In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string .
What happens to the period of the wave?
The period of a wave is indirectly proportional to the frequency of the wave : T=1f T = 1 f . The speed of a wave is proportional to the wavelength and indirectly proportional to the period of the wave: v=λT v = λ T . This equation can be simplified by using the relationship between frequency and period: v=λf v = λ f .
