Question

Distance from Starting Point of Spring (inches) 6 2 1 7 Weight on Spring (kilograms) Part A According to the graph, what is the constant of proportionality in kilograms per inch? (Note: This is also called the spring constant. The spring constant is determined by the spring's material and design.) ​

Answer 1

The constant of proportionality is the number of kilograms that will stretch the spring by 1 inch. When y = 1, x = 1/3, so the constant of proportionality in kilograms per inch is 1/3.
