To make a line graph:
The independent variable is plotted on the X-axis. When you are comparing something over time, time is the independent variable.
The dependent variable is plotted on the Y-axis.
Decide on an appropriate scale for each axis and add your scales to the X and Y axes.
Label each axis - Put the independent variable / time on the X-axis. Put the dependent variable / unit of measurement on the Y-axis.
Plot your points.
Draw your line.
Title your graph with a descriptive title (ex. The relationship between …).
Copy your average data only from the Lesson 5 Uncover pendulum investigation in the table below (data should be in your Google Doc from this lab). Be sure to descriptively name your table and graph, and include scales, points, and labels for the x- and y-axes on the line graph.
After watching this Michigan Tech pendulum video, analyze the data in Table 2 and create a line graph. Be sure to descriptively name your table and graph, and include scales, points, and labels for the x- and y-axes on the line graph. (Stop the video at 1:53).
What observations do you have about the shape of graph #1?
Based on graph #1, what can you say about how kinetic energy relates to mass?
What observations do you have about the shape of graph #2?
Based on graph #2, what can you say about how kinetic energy relates to speed?
Which impacts the amount of kinetic energy more: speed or mass? Why?
