Cards (4)

step 1
measure the natural length of the spring with a mm ruler clamped to the stand
step 2
add a mass to the spring and allow it to come to rest
record the mass and measure the new length of the spring
the extension is the change in length
step 3
repeat this process 6+ times
step 4
on the graph the curve represents exceeding the limit of proportionality
