Release the ball and watch the energy bars trade: gravitational potential energy falls as kinetic energy rises, while the total stays fixed. The speed at the bottom comes from mgh = half m v squared.
MissionDrop the ball, then predict how the landing speed of a heavier and a lighter ball compare.Streak 0Best 0
Two balls of different mass dropped from the same height reach the bottom with:
drop height h6 m
GPE remaining118 J
KE gained0 J
current speed0.0 m/s
Energy is conserved: GPE lost = KE gained. v = sqrt(2g(height fallen)), independent of mass.
