Overview
ANALYSIS PART 1
- Are the net force on an object and the acceleration of the object directly proportional? Explain, using experimental data to support your answer.
- What are the units of the slope of the force vs. acceleration graph? Simplify the units of the slope to fundamental units (m, kg, s).
- For each trial, compare the slope of the regression line to the mass being accelerated. What does the slope represent?
- Write a general equation that relates all three variables: force, mass, and acceleration.
PART 2
- For a), describe the plot. What is the value of the slope? Considering the scatter in the data points, do you think the slope is significantly different from zero? If it is zero, explain why? Is there any significant feature of the plot that relates to the value of some physical quantity in the experimental setup?
- For b), describe the plot. What are the important features? What is the value (plus units) of the slope? Explain why the slope has this value.
