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.) The acceleration of the object doubles when net force is doubled. Identify a set of two trials that support your answer above: 1,2 Net Fence Acceleration (m/ Trial N 2. What affect does a tripling of the net force have upon the acceleration of the object? Be Tri quantitative. The acceleration of the object increases by a factor of times 3 when net force Identify a set of two trials that support your answer above: 2,4 Net Force Acceleration Purpose: The purpose of this activity is 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.

What affect does a quadrupling of the mass have upon the acceleration of the object? Be quantitative. The acceleration of the object by a factor of times 4 when mass is quadrupled. Identify a set of two trials that support your answer above: 7,9 Net Force Acceleration (m/s) Trial (N) 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. They cannot be used because to many variables are changed, it wont be accurate with both mass and net force are different. Net Force Trial (N) Acceleration (m/s) Conclusion: 3. What affect does a doubling of the mass have upon the acceleration of the object? Be quantitative. Doubling the mass of objects halves it acceleration Identify a set of two trials that support your answer above: 3,7 Net Force Acceleration (m/s) Trial (N) 4. What affect does a quadrupling of the mass have upon the acceleration of the object? Be quantitative. The acceleration of the object by a factor of times 4 when mass is quadrupled.
