Question
A spring is compressed by 0.15 m and stores 2.25 J of elastic potential energy. Calculate the spring constant of the spring.
Answer
The spring constant of the spring is 100 N/m.
Explanation
This answer stays anchored to Changes in energy and uses the approved objective: Calculate elastic potential energy stored in a stretched spring within its limit of proportionality..
Common mistake
Misunderstanding Elastic Potential Energy Calculation
Students often confuse the elastic potential energy formula Ee = 0.5 x k x e^2 by misidentifying the spring constant (k) and extension (e).
Ensure to correctly identify k as the spring constant in N/m and e as the extension in meters before substituting values into the formula.
