Potential Energy
A spring is shortened by \(2\text{ m}\) from its original length. If the elastic potential energy of the spring is \(10\text{ J},\) what is the value of the spring constant?
A spring hanging from the ceiling has a length of \(4\text{ m},\) and its spring constant is \(k=20\text{ N/m}.\) If the spring is pulled so that its length gets doubled, what is the elastic potential energy in the spring?
An object is at rest on a frictionless surface is attached to the wall by an elastic spring of strength \(\SI[per-mode=symbol]{10}{\newton\per\meter}.\)
A force of strength \(F=40\text{ N}\) pulls the object toward the right.
What is the elastic potential energy of the spring at equilibrium?
The spring in a monster truck's suspension is shortened by \(4\text{ m}\) from its original length. If the spring constant is \(k=2\text{ N/m},\) what is the elastic potential energy of the spring?
