Question

A student graphs the movement of a motorized cart across the football field. Identify the dependent variable in this graph.

Answer 1

Answer:

Velocity.

Explanation:

The dependent variable is dependent on the independent variable. Basically, in order for the dependent variable to happen, the independent variable needs to do something first. Usually on a graph, x is the independent variable, and y is the dependent variable. In this situation, the time (x) needs to be graphed in order to track the velocity (y) on the graph.

The other answers are valid, but are not listed on the graph. Unless something is implied with a specific answer (like saying that speed and velocity are considered one on one side of the graph), the other answers wouldn't be correct.

I hope this helps.

Answer 2

Explanation:

Dependent variables receive this name, because in an experiment they depend by some rule on the values of other variables.

here, time (in seconds) is all measured by itself.

but velocity is a measurement that depends on 2 input values : distance (m) and time (s).

so, velocity is the dependent variable.
