Force Interactive Frictionless Situations Aim: To investigate the variables that affect the acceleration of an object and the manner in which those variables affect the acceleration. Background: When forces are unbalanced, objects accelerate. But what exactly affects the acceleration of the object? You will explore this question by running a collection of simulations in the absence of friction. Set the friction value to 0.00 and run the following trials. Collect sufficient velocity-time information (fifth column) for determining the acceleration in the last column. Data: Trial 1 2 3 4 5 6 7 8 9 10 Applied Force 10.0 20.0 40.0 60.0 80.0 100.0 40.0 40.0 40.0 40.0 Mass Net Force VelocityTime Informatio n 2.0 2.0 2.0 2.0 2.0 2.0 1.0 3.0 4.0 5.0 Use the collected data to answer the questions in the Analysis section. Analysis: 1. What affect does a doubling of the net force have upon the acceleration of the object? Be quantitative. (Don't just say it decreases or increases; indicate the factor by which acceleration decreases or increases.) Identify a set of two trials that support your answer above: What affect does a tripling of the net force have upon the acceleration of the object? Be quantitative. Identify a set of two trials that support your answer above: Acceleratio n (m/s/s) 2. What affect does a doubling of the mass have upon the acceleration of the object? Be quantitative. Identify a set of two trials that support your answer above: 3. What affect does a quadrupling of the mass have upon the acceleration of the object? Be quantitative. Identify a set of two trials that support your answer above: 4. Lab partners Vera and Bill Confuzzens attempted to use Trials 5 and 8 to show the effect that a doubling of force has upon the acceleration. Explain why these two trials cannot be used to show the affect of force upon acceleration. Conclusion: Consider the original question that prompted this investigation: What variables affect the acceleration of an object and in what manner do they affect the acceleration? Make a claim in which you attempt to answer this question. Then support the claim with evidence (specific references to trials of data) and reasoning in which you explain how the data support the claim that you have made.
