Question
A spring has a spring constant of 200 N/m and is extended by 0.3 m. Calculate the elastic potential energy stored in the spring.
Answer
9 J
Explanation
The calculation uses the formula for elastic potential energy, which is directly related to the spring constant and the extension. This question tests the ability to apply the formula correctly to find the energy stored in a spring.
Common mistake
Common Mistake in Elastic Potential Energy Calculation
Students often confuse the extension in the elastic potential energy formula, using total length instead of just the extension from the original length.
Ensure to measure extension as the increase in length from the original length of the spring, not the total length.
