Frequently asked questions
- What is the reference height?
- PE is always relative to a chosen reference (usually the ground). Only differences in PE matter for energy calculations.
- How is PE related to KE?
- In a frictionless fall, PE converts entirely to KE: mgh = ½mv², giving v = √(2gh) at impact.
