Energy Conservation: In a frictionless descent to height zero, 100% of the potential energy converts into kinetic velocity.
Kinetic vs Potential Energy Split
Detailed Calculation Breakdown
Calculation Methodology
Kinetic Energy: KE = 0.5 * m * v². Potential Energy: PE = m * g * h (g ≈ 9.80665 m/s²). Total Mechanical Energy = KE + PE.
