Exam-style question
Try this first
A spring is compressed by 0.3 m and has a spring constant of 150 N/m. Calculate the elastic potential energy stored in the spring.
Model answer
What a good answer should say
- The elastic potential energy stored in the spring is 6.75 J.
Explanation
Why this works
This question assesses the understanding of elastic potential energy calculation. It requires substituting the spring constant and extension into the formula and calculating the energy stored due to compression.
