A bungee jumper is standing at the edge of a platform, just about to leap over the side. Midway through the jump, while the bungee jumper is halfway down to the ground, what is the relationship between potential and kinetic energy? There is only kinetic energy at this point.
Potential energy has decreased, and kinetic energy has increased.
Potential and kinetic energy are both zero.
Kinetic energy has decreased, and potential energy has increased.
