Read the wording for your board, then hide it and explain Energy–displacement relationships in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
At any displacement x, kinetic energy is ½mω²(A² − x²) and potential energy is ½mω²x², so their sum is constant.
