From The Physics Classroom’s Physics Interactive http://www.physicsclassroom.com Force Interactive Frictionless Situations 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. Data: Trial Applied Force (N) Mass (kg) Net Force (N) Velocity-time Information Acceleration (m/s/s) 1 10.0 2.0 10.00 N (1.0 s, 5.00 m/s) (5.0 s, 25.00 m/s) 5 m/s^2 2 20.0 2.0 20.00 N (1.0 s, 10.00 m/s) (5.0 s, 50.00 m/s) 10 m/s^2 3 40.0 2.0 40.00 N (1.0 s, 20.00 m/s) (4.0 s, 80.00 m/s) 20 m/s^2 4 60.0 2.0 60.00 N (1.0 s, 30.00 m/s) (3.0 s, 90.00 m/s) 30 m/s^2 5 80.0 2.0 80.00 N (1.0 s, 40.00 m/s) (3.0 s, 120.00 m/s) 40 m/s^2 6 100.0 2.0 100.00 N (1.0 s, 50.00 m/s) (3.0 s, 150.00 m/s) 50 m/s^2 7 40.0 1.0 40.00 N (1.0 s, 40.00 m/s) (3.0 s, 120.00 m/s) 40 m/s^2 8 40.0 3.0 40.00 N (1.0 s, 13.33 m/s) (4.0 s, 53.33 m/s) 13.33 m/s^2 9 40.0 4.0 40.00 N (1.0 s, 10.00 m/s) (5.0 s, 50.00 m/s) 10 m/s^2 10 40.0 5.0 40.00 N (1.0 s, 8.00 m/s) (5.0 s, 40.00 m/s) 8 m/s^2 Use the collected data to answer the questions in the Analysis section. ©The Physics Classroom, All Rights Reserved

From The Physics Classroom’s Physics Interactive http://www.physicsclassroom.com This document should NOT appear on other websites. 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.) When the applied force is doubled, it is evident from trials two and three that the acceleration also doubles. In these trials, the applied force increased from 20.00N to 40.00N, resulting in an acceleration increase from 10m/s^2 to 20m/s^2. Identify a set of two trials that support your answer above: 2 and 3 2. What affect does a tripling of the net force have upon the acceleration of the object? Be quantitative. Tripling the applied force results in a tripling of the acceleration, as demonstrated in trials two and four. The acceleration increased from 10m/s^2 to 30m/s^2. Identify a set of two trials that support your answer above: 2 and 4 3. What affect does a doubling of the mass have upon the acceleration of the object? Be quantitative. In trials three and seven, where the applied force remained constant but the mass was doubled, it becomes evident that the acceleration also doubles, transitioning from 40m/s^2 in trial seven to 20m/s^2 in trial three. Identify a set of two trials that support your answer above: 3 and 7 4. What affect does a quadrupling of the mass have upon the acceleration of the object? Be quantitative. Observing trials seven and ten, we notice that when the mass is quadrupled, the acceleration decreases by a factor of five when the mass is heavier. Identify a set of two trials that support your answer above: 7 and 10 4. 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
