Common mistake
Confusing Units of Measurement
Students often confuse elastic potential energy measured in joules with spring constant measured in newtons per metre.
Remember that elastic potential energy is always expressed in joules, while the spring constant is expressed in newtons per metre. Keep the units distinct when solving problems.
