Want this question answered?
A shorter pendulum has a shorter period. A longer pendulum has a longer period.
The single effect in The Pit and the Pendulum is that of mind-numbing fear, depression and hopelessness
At the center of the Earth there would be no effective gravity; a pendulum wouldn't work as a pendulum.
no it doesnt affect the period of pendulum. the formulea that we know for simple pendulum is T = 2pie root (L/g)
Assuming the pendulum referred to s asimple pendulum of an arm and a weight the major factors on the period are the local attraction of gravity and the length of the arm.
The length of the pendulum, the angular displacement of the pendulum and the force of gravity. The displacement can have a significant effect if it is not through a small angle.
If none of the variables are constant (or controls) you have no idea which variable or combination of variables caused the effect.
In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
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.
You measure the period of the pendulum for different lengths. Plot the results on a scatter plot and see if you can work out the nature of the relationship between the two variables.
The variable YOU change which will in turn effect another variable (the dependent variable). The controlled variable is plotted on the x - axis of a graph.
all variables have been carefully operationalised
Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used. Dependent variables are those which change due to the conditions mentioned above. These might be speed of the reaction, or the quantity of some product.
controlled experiment
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
A shorter pendulum has a shorter period. A longer pendulum has a longer period.
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
