2024 Graphing Data Pretest

Front

What is the y-axis in a graph?

Back

The y-axis is the vertical line on a graph that represents the dependent variable, which is affected by the independent variable on the x-axis.

Front

What does a graph showing energy at a point on a track represent?

Back

It represents the amount of energy at that specific point, which can vary based on factors like height and speed.

Front

What happens to momentum when two skaters push off each other?

Back

The total momentum before and after the push remains the same, but the skaters will have different speeds based on their masses.

Front

How do you determine which graph represents a scenario of constant speed followed by a stop and then increased speed?

Back

Look for a graph that shows a straight line (constant speed), a flat line (stop), and then a steeper line (increased speed).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing how much motion an object has.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does it mean for a graph to be linear?

Back

A linear graph shows a constant rate of change, represented by a straight line.

Front

What is the independent variable in a graph?

Back

The independent variable is the variable that is manipulated or changed in an experiment, typically plotted on the x-axis.

Front

What is the dependent variable in a graph?

Back

The dependent variable is the variable that is measured or observed in an experiment, typically plotted on the y-axis.

Front

How can you identify the slope of a graph?

Back

The slope of a graph is determined by the rise over run, which indicates the rate of change between the two variables.
