Answer
A) Potential to kinetic.
B) Kinetic to potential and potential to kinetic.
C) Potential to kinetic
D) Potential to kinetic.
Work Step by Step
A) Potential to kinetic.
B) Kinetic to potential and potential to kinetic: player's leg velocity is converted in elastic deformation of the ball which accelerates it by returning to its original shape.
C) Potential to kinetic: electron motion.
D) Potential to kinetic: increase in velocity of molecule motion
