A bouncy ball is dropped from a height of 100cm. When the ball bouncy back up, it only goes to a height of 70 cm. The reason for this is because some of the balls kinetic energy is transferred to the molecules in the air as well as to the ground with each consecutive bounce. What law of energy is being observed in the bouncy ball.

The conservation of energy
