Governing Formulas & Engineering Theory
PE = m * g * h, v_impact = sqrt(2 * g * h)
Potential energy represents stored gravitational energy. By conservation of energy, all potential energy converts into kinetic energy at ground impact.

Frequently Asked Questions
Does potential energy depend on the path taken?
No, gravity is a conservative force, so potential energy depends strictly on the initial and final vertical elevations.
How do hydroelectric power plants utilize potential energy?
Water stored at elevated reservoir height converts gravitational potential energy into mechanical turbine torque, driving electric generators.
How do you calculate impact velocity from height h?
v = sqrt(2 * g * h), independent of mass when neglecting aerodynamic drag.
