(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: 2. 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: 3. 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: 4. 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: 5. Lab partners Vera and Bill Confuzzens attempted to use Trials 5 and 8 to show the affect 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. ©The Physics Classroom, All Rights Reserved This document should NOT appear on other websites.
From The Physics Classroom’s Physics Interactive http://www.physicsclassroom.com 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. ©The Physics Classroom, All Rights Reserved This document should NOT appear on other websites.
