🔧 How to Rearrange the GPE Equation
Starting equation: Ep = mgh
To find mass: m = Ep / (g × h)
To find height: h = Ep / (m × g)
To find g: g = Ep / (m × h)
💡 Exam tip: Height must be VERTICAL. If an object moves along a slope, only use the vertical height change in your GPE calculation, NOT the distance along the slope.
