A spring of spring constant 50 N/m is stretched by 0.02 m. How much elastic potential energy does it store?
Answer and explanation
Correct answer: B. 0.01 J
- Step 1: Elastic potential energy .
- Step 2: J.
Answer
0.01 J.
Why not the others: 0.02 J: the factor is missing. 0.5 J: the extension is not squared. 1 J: that is the force, not the energy.
