| In an experiment, a student applied various
forces to a spring and measured the spring's corresponding elongation. The table
below shows his data. |
|
|
13. On the grid below,
plot the data points for force versus elongation. 14. Draw the best fit line
|
 |
| 15. Using your graph, calculate the spring constant of the spring. [Show all work, including the equation and substitution with units.] | |
|
Base your answers to questions 16 through 19 on the graph below, which represents the relationship between vertical height and gravitational potential energy for an object near Earth’s surface. |
|
 |
16. Based on the graph,
what is the gravitational potential energy of the object when it is 2.25
meters above the surface of Earth? ________________________ 17. Using the graph, calculate the mass of the object. [Show all work, including the equation and substitution with units.]
18. What physical quantity does the slope of the graph represent? _______________________ 19. Using a straightedge, draw a line on the graph to represent the relationship between gravitational potential energy and vertical height for an object having a greater mass. |
