Investigation Newton's Second Law Purpose: To investigate the relationship between the applied force and the acceleration in a frictionless environment. Materials: Macromedia Flash Player and the Flash animation "Acceleration vs. Force" Procedure: 1. Ftun the above program ..... can't due to Flash not working anymore. 2. Forces of i) 1 M, ii) 2 M, iii) 3 N, iv) 4 N were selected and each resulting acceleration was recorded in the chart below. m fonvar I Acceleration I150 1.0 1.5 2.0 mt fonrvard Analysis: 1. Using the data in the above chart. create a Force vs. Acceleration graph {plot the force on the vertical axis even though it was the independent variable). After plotting the points, join the points with a smooth line. What is the shape of the line? 2. Ely viewing the graph, predict what the acceleration would be for a Force of E N [forward]. Explain your reasoning. 3. In a frictionless environment, what type of mathematical relationship exists between the Acceleration and the Applied Force? Choose from the following two possibilities. i} Two variables are said to be directly proportional if doubling the independent variable [force in this case) caused the dependant variable (acceleration in this case) to double. i0 Two variables are said to be inversely proportional ii doubling the independent variable causes the dependent variable to become one half the size. 4. The effect of mass on acceleration was not investigated in this simulation. However. mass also has an effect on acceleration. Which of the mathematical relationships described in #3 exists between mass and acceleration? Explain your reasoning. 5. Find the slope of the graph with its units. Is it constant? How does it fit into Newton's second law? If we made this constant larger and plotted the results of the force on acceleration, would the line be steeper or less. Explain your reasoning
