Displacement vs Time in Uniform Motion

 The slope of the line above represents the velocity (v = 1.08 m/s). What does the intercept represent? Answer in the comments section below.

One more attempt to graph displacement vs time

Both graphs are done by Lenicha in Excel. Good job! 

Just one observation.  In the graph below, points are precisely placed on a parabola (trendline option of a second-degree polynomial).  That suggests a question about the graph above, which presents quite scattered points.  The only reasonable explanation is in the launching method; the launcher equipped with a rubber band might not be the best solution.  

Both graphs present a good start-point for further discussion in class. 

Measuring Velocity with an Air Track

Experiment by Jenny, Jung, and Manuel

Uniform motion

This setup was used to determine the change in position of the glider in time in the uniform motion. Below there is a graphical representation of the findings.

The graph was done in Excel. Slope of the regression line represents the actual speed of the glider.
