High institution Physics help » Introductory values » understanding Independent and Dependent Variables

A scientist actions how much a fragment travels in ~ a provided amount the time. Every 2nd she measures how far it has gone, and also creates a graph of she results. What is the independent change in this experiment?


Explanation:

An independent variable is manipulated by the experimenter. Any changes made room predictable. The dependent variable reaction to changes made to the independent variable. Its transforms are not regulated by the experimenter and also can be difficult to predict.

You are watching: Does independent variable go on x axis

In this details experiment, the scientist is measuring exactly how the particle"s distance transforms over a given time. She is able to manage the amount of time the she measures, but is only able to watch the street traveled.

In the graph, the live independence variable will certainly be graphed ~ above the x-axis.

Example concern #2 : expertise Independent and Dependent Variables


When looking in ~ velocity in regards to distance and also time, what is the elevation variable?


Possible Answers:

Time


Acceleration


Displacement


Velocity


Distance


Correct answer:

Time


Explanation:

There room a couple of ways come think that this question. The an initial is to imagine you room graphing velocity. Since the equation is

*
, the displacement would be ~ above the y-axis and time would be top top the x-axis. The x-axis is going to be whereby we placed our independent variable.

The other way to think of this is to ask you yourself what our "inputs" and also "outputs" would certainly be if we were measuring velocity. Imagine you"re walking under the street and you record how far you take trip every second. The moment is what you space "inputting" and also your distance took trip is your "output."

Example concern #3 : knowledge Independent and also Dependent Variables


You space looking at a graph of the motion of a vehicle. Top top the y-axis is displacement and on the x-axis is time. Which of the following is the live independence variable?


Possible Answers:

Acceleration


Velocity


Distance


Displacement


Time


Correct answer:

Time


Explanation:

Independent variables are predetermined by the experimenter and also can be manipulated to change the measure dependent variable. Live independence variables are usually graphed on the x-axis, when dependent variables are usually graphed on the y-axis.

In this question, time is the elevation variable and also displacement is the dependent variable. The experimenter can pick sampling times, yet cannot have to predict the displacement that will be measure at each point. This specifies time as the elevation variable.

Example inquiry #4 : understanding Independent and Dependent Variables


Where is the independent change most commonly displayed ~ above a graph?


Possible Answers:

Along both the x- and y-axes


Sometimes along the x-axis and sometimes along the y-axis


Along the x-axis


The independent change is not displayed


Along the y-axis


Correct answer:

Along the x-axis


Explanation:

The independent change is managed by the experimenter, if the dependent variable will certainly fluctuate based upon independent variable inputs. The independent change is always displayed top top the x-axis the a graph, while the dependence variable shows up on the y-axis. Time is a typical independent variable, together it will certainly not be affeced by any dependent environemental inputs. Time deserve to be treated as a controllable consistent against which transforms in a system can be measured.
