Place the cabinet back at the -7 meters. Remove the graph of the applied force. 10. Apply a constant force of 100 N. You can do this by typing the value in the applied force in the simulation. 11. Click play and watch the cabinet move. On the graph find the average acceleration. 12. Fill out table 1 for the average acceleration of the cabinet. 13. Change the object by using the control panel on the right. Push the object with a constant force of 100 N. 14. Find the average acceleration from your acceleration graph and fill out table 1 for the average acceleration for the object. Table 1: Average Acceleration versus Mass Object Mass (kg) File Cabinet Average Acceleration (m/s) Refrigerator 0.5 Textbook D.2 Crate aT 300 Sleepy Dog 15. Graph the average acceleration versus mass using Table 1 using Excel or another spreadsheet program. Add a trendline to your graph that best fits the data. Include your graph with trendline to your worksheet Question 8: How does the applied force compare to the slope of the graph, that you found from the trendline? - From the graph F= slope = Applied Force= 113141 N which is greater than actual Question 9: Write the equation relating mass, acceleration, and force. applied Force of loom.. According to Newton's second law of motion, the relatinghip between mass, Accelerate Activity 4: Friction lon and Force is expressed QS 16. Bring the object back to -7 m. Set the friction option to "On". Force = MQ 17. Remove the graph for acceleration. Add the graph for applied force. 18. Add force until the object starts to move and once the object starts to move let it move for a second or two. 19. Use the graph to find the maximum force required to bring the object into motion. Use the graph to find the frictional force once the object is in motion. Fill out Table 2 for each table.

Use your results to justify. 20. Choose the textbook object. Set the force to be 100 N. Make sure the option for Friction is still on. 21. Display the graphs for applied force and acceleration. 22. Calculate the acceleration of the book with this force. Show your work. 23. Press play in the simulation. Once the textbook is off the screen pause the simulation. Question 11: Using the graphs what was the applied force, friction force, net force, and acceleration? Force: 755 m/2 Applies Force = 100 N / Friction Force= 24.5N Question 12: Was the acceleration the same as what you calculated? Use the net force from the graph to calculate the acceleration, show your work. Was this value the same as the one measured in the simulation? -Net force = mass X acceleration : 7.55Question 13: Using your results from question 12 write the more accurate equation relating force, mass, and acceleration. Use the sum of forces, or net force . Question 14: There are two forces acting in the vertical direction, what are these two forces and why is the textbook not accelerating in the vertical direction? - The two forces acting on vertical direction are gravitation as Force . Question 15: The spring scale in the diagram below reads 10.5 N. - Normal Force is equal to the weight of the object. There Forces are not Shown since normal Force Ans page 4 of an Object at rest On a Flat Surface is equal FA to gravititional Force on the Doject If the cart moves toward the right with an acceleration also toward the right of 3.25 m/s?, what is the mass of the cart? You can ignore friction. Show your calculations. Question 16: The force applied to the cart in Question 15 by spring scale FA is still 10.5 N. The cart now moves toward the right with a constant velocity. What are the magnitude and direction of the frictional force? Show your calculations and explain your reasoning. Question 17: The force applied to the cart in Question 15 by spring scale FA is still 10.5 N. The cart now moves towards the right with an acceleration also toward the right of 1.75 m/s?. What are the magnitude and direction of the frictional force? Show your calculations. Question 18: The force applied to the cart in Question 15 by spring scale FA is still 10.5 N. FB FA The cart now moves to the right with a constant velocity. The frictional force is the same as in Question 17. What does the spring scale F: read?
