What is the effect of mass on number of swings in pendulum experiment?

While we consider the pendulum experiment, we consider so many assumptions that the string is inelastic and there is no air friction to the movement of the bob.
With all these, we derive the expression for the time period of the pendulum as
T = 2 pi sqrt (l/g)
Here, in no way, mass of the bob comes to the scene.
So, mass of the bob does not have any effect on the time period or its reciprocal value, namely, frequency. ie number of swings in one second.

What is the number of back and forth swings a pendulum makes is called?
If you mean the time it takes to swing from start to finish (top to top) this is called the period and if it is the number of swings per second this is know as the frequency.
Why are variables important in a science investigation?
I got this from bcps.org.The procedure used in an experiment must be written in a clear, sequential mannerin order to allow someone else to follow the same steps to replicate the experiment.Numbering the steps followed in the procedure is helpful to someone who is readingthe procedure. In determining the procedure that will be used in the investigationthe factors that will affect the outcome of the experiment, called variables, mustbe identified and controlled. There are three types of variables that must beconsidered:• Independent variable (manipulated variable) - the factor that will beintentionally changed during the experimental procedure in order to find out whateffect it has on something else. An example of an independent variable is usingdifferent lengths of string to construct a pendulum in order to observe the effectthe length of the string has on the swing of the pendulum.• Dependent variable (responding variable) - the factor that is observed andmeasured to see if it is affected by the change made in the independent variable.An example of a dependent variable is the number of swings the pendulum makeswhen the length of its string is changed.• Variables that are controlled - the factors in the experiment that must be keptexactly the same to make sure that they are not having any effect on the dependentvariable. Variables that would need to be controlled in the pendulum experiment wouldbe the mass of the pendulum, the type of string, and the release height of the pendulum.============================Great copying job!Now we know what they are.But why are they important ? ! ?The question still needs an answer.
Discussion and calculations of compound pendulum due to gravity?
DISCUSSION From the experiment, I found that there are several differences in between theoretical values and experimental values that being obtained. These differences should not be so obvious. The values supposed to be not much in difference as the experimental and theoretical values should be almost the same. By my inference, there are several factors that influenced these differences. One of the main factors that often occur in any experiment including this experiment is inconsistency while values are taken. Firstly, the hinge where the pendulum is hang is an 'allen key' and have 6 surfaces which is not smooth. Thus, the pendulum cannot swing smoothly compared if the hinge used is a smooth circular rod. While the pendulum is released, the angle where the pendulum is released is not accurate. The angle of released are not always the same each time, even the angle supposed to be at since the measurement of the angle is only depended on the protactor which is hold next beside the pendulum. Moreover, the angle is observed with our eyes and at different position. Thus, accuracy in this matter is questionable. Other than that, the time taken for the pendulum swing is also questionable as it is observed also with our eyes. The point where the pendulum starts and ends after ten consecutive swings are not really exact as we cannot really measure when the pendulum change it direction to a reversed swing. The time taken when the pendulum completed ten swin9gs is also not accurate. Even this matter seemed to be unreliable, actually it affects our readings a lot when it comes to calculation. Besides that, the area where this experiment is held is close to the laboratory entrance door and wind is also the factor for the pendulum to swing inconsistently as the wind speed changes all the time. There are times when wind blows quite fast and there are times when no wind blows at all. Thus, all of the factors above do influence the readings taken throughout this experiment and that is why the results vary in some way.
How is energy transferred during a pendulum swing?
A swinging pendulum has potential energy at each end of it's travel (when it stops momentarily) This energy is converted to kinetic energy as it swings down and back to potential energy as it swings up the other way.
How would science be different without the scientific method?
Strictly speaking, most scientists would argue that there is no such thing as The Scientific Method. Scientists adopt a wide variety of methods to get closer to the truth in different problem situations.There are, however, lots of cases where a more scientific approach has brought us better understandings. Galileo, for example, did not just watch a chandelier swinging like a pendulum. He counted the number of swings over a fixed period of time (he measured time by using his heartbeat) He took measurements when the chandelier was swinging in big and small swings. He repeated the experiment changing one variable at a time., using pendulums with different weights or different lengths, for example. He looked for mathematical relationships between the numbers he obtained and so on. From our modern viewpoint, you might say that if he had not done these things he was not "doing Science" as we currently understand it.
What is the relationship between the length of the string of a pendulum and the number of swings?
There's no relationship between the length of the pendulum and the number of swings.However, a shorter pendulum has a shorter period, i.e. the swings come more often.So a short pendulum has more swings than a long pendulum has in the same amountof time.
Which variables made no difference in the number of swings?
Assuming that this question concerns a pendulum: there are infinitely many possible answers. Among these are: the name of the person swinging the pendulum, the colour of the pendulum, the day of the week on which the experiment is conducted, the mass of the pendulum, my age, etc.
What is the number of swings a pendulum makes in 10 swings?
I'd guess that if it swings 10 times, it makes 10 swings.
Which length of the pendulum made the most number of swing?
The shorter the pendulum the more swings you get.
Which length of the pendulum made the most number of swings?
A shorter pendulum will make more swings per second. Or per minute. Or whatever.
What Is The Independent And Dependent Variables in Galileo Pendulum experiment?
Galileo's pendulum experiment showed that the period of the swing is independent of the amplitude (size) of the swing. So the independent variable is the size of the swing, and the dependent variable is the period. The experiment showed there was no dependence, for small swings anyway. The experiment led to the use of the pendulum in clocks.
What energy changes occur as a pendulum swings?
when a pendulum swings it creates pontential energy
Does the length of a pendulum effect how it swings?
Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.
What is the amount of error when using a stopwatch in the simple pendulum experiment and by repeating the amount of swings when timing does this make it more accurate?
no.
Does a 45 cm pendulum have less swings then a 38 cm pendulum and why?
A pendulum swings as far out as you care to set it going, irrespective of length.
Is the relationship between the number of pendulum swings and time direct or inverse?
swings = cycles x time ; it is a direct relationship with time
What are the release dates for Pendulum Swings - 2011?
