Emission of light from an atom occurs when an electron

Which is an example of transfroming potential energy to kinetic

Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that's above the ball.
