3. Measure the distance from the bottom of the spring to the tabletop

or floor.

4. Subtract the "initial distance" from the new distance to calculate

the stretch of the spring. Record this value in a data table.

5. Place more mass on the spring and repeat measurements/

calculations.

6. Collect at least six pairs of hanging mass and stretch data.

7. Convert the hanging masses to force using the acceleration due to

gravity:

8. Create a graph with force on the vertical axis and stretch on the

horizontal axis.

9. Using y = mx + b, write an equation for each of the lines. Make

sure to include appropriate variables, numbers, and units in the
equation.

10. The slope of the Force vs. Stretch graph in known as the spring

constant or rate. The vertical intercept represents the amount of
force needed to begin stretching the spring and is also known as
the initial tension.
