Three identical springs are used to hang different weights. Spring A has 100g, Spring B has 200g, and Spring C has 300g. Which spring will have the greatest amount of elastic potential energy?

A All will have the same energy
B Spring B
C Spring C
D Spring A
Show Worked Solution

Worked Solution

Step 1: Elastic potential energy increases with the amount of extension. Step 2: A heavier weight causes more extension in a spring. Step 3: Spring C has the most weight, so it has the most energy.

Correct answer: Spring C
