The amount of stretch of a hanging spring versus the mass attached to the bottom of the spring was measured for different masses. The results are shown mass (grams) 2 4 8 10
stretch (centimeters) 4 8 16 20
What is the constant of proportionality between the mass and the amount of stretch?
0.5 centimeters per gram
O 0.5 grams per centimeter squared
2.0 centimeters per gram
