Question
What is the equation for calculating elastic potential energy in a spring?
Answer
The equation for calculating elastic potential energy (Ee) in a spring is Ee = 0.5 x k x e², where k is the spring constant and e is the extension of the spring.
Explanation
This question tests the student's understanding of the relationship between elastic potential energy, spring constant, and extension. It requires recall of the specific formula used in calculations involving elastic potential energy.
Common mistake
Common Mistake in Elastic Potential Energy Calculation
Students often confuse the extension in the elastic potential energy equation, using total length instead of just the extension.
Always ensure to measure the extension as the increase in length from the original length, not the total length of the spring.
