The energy you put into the ball was the result of “work”. The energy of the work you perfored came from Chemical Potential Energy in your body, unlocked by burning calories.
According to the law of Conservation of Energy, there is a constant amount of energy in an “isolated” system. The energy of the calories is turned into work, and is stored in the ball when it is lifted. When the ball (lets say it’s a bowling ball for dramatic effect) is released, gravitational potential energy takes the form of kinetic energy. When the ball hit’s the ground the energy is converted back to heat and sound (the kinetic energy of air molecules). The heat is dissipated but remains in the system and so does the energy of sound the waves.
It’s interesting to note by lifting the ball you increased it’s potential energy relative to the surface but you decreased the force of gravity between the center of the earth and the center of the ball.
