Question
What is the equation for calculating elastic potential energy stored in a stretched spring?
Answer
The equation for calculating elastic potential energy (Ee) stored in a stretched spring is Ee = 0.5 x k x e^2, where k is the spring constant and e is the extension of the spring.
Explanation
This question tests the student's ability to recall the specific equation related to elastic potential energy, which is a fundamental concept in physics regarding energy stored in elastic materials.
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.
