mass such that its zero mark is even with the dashed reference line, and read off the distance from
the reference line to the bottom of the spring (the horizontal red line).
This is the distance the
spring has stretched as a result of the mass being attached to it.
Fill out the first row of the first data table, being sure to record the appropriate units in the
column headings at the top.
Note that weight = mass * gravity, but the mass must be converted to
kilograms in order for the weight to be in Newtons.
In equilibrium, the spring force is equal to
the weight attached to it.
Remove the 250 g mass from spring 1, and attach the 50 g mass.
Measure the distance that the
spring is stretched, and fill out the second row of the data table.
Repeat again for one of the 100 g
masses, and record the results in the third row.
Repeat the entire procedure for spring 3, and record the results in the second data table.
sure the softness of the spring is set as specified earlier.
If you have not already done so, fill in the following tables with the values you found in the
