Common questions
What is the Spring Potential Energy formula?
Spring Potential Energy is written PE = 1/2kx². Elastic potential energy stored in a spring. It belongs to Mechanics, under Work & Energy.
What are the units in PE = 1/2kx²?
In SI units, PE is potential energy, measured in kg·m²/s²; k is spring constant, measured in kg/s²; x is displacement, measured in m.
How is the Spring Potential Energy formula derived?
Work to stretch spring: W = ∫kx dx = ½kx². The result is PE = 1/2kx².
