Which variables must be controlled when determining the effect of mass on the period of the pendulum?
When determining the effect of mass on the period of a pendulum, you must control the length of the pendulum and the angle at which it is released. By keeping these variables constant, you can isolate the effect of mass on the period of the pendulum for a more accurate comparison.

What effect does the acceleration due to gravity on the moon have on a simple pendulum?
The lower acceleration due to gravity on the moon causes a simple pendulum to swing more slowly compared to Earth. The period of the pendulum is longer on the moon because gravity plays a role in determining the speed at which the pendulum swings back and forth.
What are factors in an experiment?

What variables did you have to control in order to get a valid result?
We controlled the independent variable (the variable we manipulated) to observe its effect on the dependent variable (the variable we measured). We also controlled for any potential confounding variables that could influence the results. Additionally, we ensured consistency in experimental conditions to eliminate any extraneous variables that could impact the outcome.
What factor has the greatest effect on the period of a pendulum?
The length of the pendulum has the greatest effect on its period. A longer pendulum will have a longer period, while a shorter pendulum will have a shorter period. The mass of the pendulum bob and the angle of release also affect the period, but to a lesser extent.
Why did we use two masses with identical geometries for the simple pendulum experiment?
Using two masses with identical geometries in a simple pendulum experiment allows for controlling variables and ensuring reproducibility of results. By keeping the mass and shape of the objects consistent, we can isolate the effect of the independent variable being tested (e.g., length of the pendulum) on the dependent variable (e.g., time period of oscillation).
What 3 variables that might affect the number of cycles the pendulum makes in 15 seconds?
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.
Why cant you draw a conclusion about the effect of one variable in an investigation when the other key variables are not controlled?
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 how many mainpulated responding and controlled variables should you have why?
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.
How do you investigate the effect on period of a pendulum if length is altered?
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.
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.
What makes an experiment controlled?
An experiment is considered controlled when all variables are kept constant except for the one being tested. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment. Controlled experiments help establish cause-and-effect relationships between variables.
What effect does the acceleration due to gravity on the moon have on a simple pendulum?
The lower acceleration due to gravity on the moon causes a simple pendulum to swing more slowly compared to Earth. The period of the pendulum is longer on the moon because gravity plays a role in determining the speed at which the pendulum swings back and forth.
In an experiment what are the controlled 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.
What word is defined as a carefully controlled scientific procedure that determines whether variables manipulated by the experimenter have a casual effect on other variables in psychology?
all variables have been carefully operationalised
How is a controlled experiment different from an observational study?
In a controlled experiment, researchers manipulate variables to observe their effect on outcomes, while in an observational study, researchers observe natural variations in variables without manipulating them. Controlled experiments allow for stronger causal inferences compared to observational studies because they can establish cause-and-effect relationships.
What is the differences between dependent variables and controlled variables in an experiment?
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.
A test of the effect of a single variable by changing it while keeping all other variables the same?
