Question
If a spring has a spring constant of 200 N/m and is extended by 0.5 m, what is the elastic potential energy stored in the spring?
Answer
The elastic potential energy stored in the spring is 25 J.
Explanation
This answer stays anchored to Changes in energy and uses the approved objective: Recall and apply the equation Ee = 0.5 x k x e^2..
Common mistake
Misunderstanding Elastic Potential Energy
Students often confuse the variables in the equation Ee = 0.5 x k x e^2, particularly mixing up the spring constant (k) and the extension (e).
To fix this, students should carefully identify each variable: k is the spring constant measured in N/m, and e is the extension in meters. Practicing with examples can help reinforce the correct application of the equation.
