Which of the following best represents potential energy being converted to kinetic energy?
a) in the chemical energy in a battery is used to power a cell phone
b) the movement of wind turns a windmill that generates electricity
c) a man petals a bicycle to ride across town
d) i want to kick the soccer ball in scores a goal

The best correct answer is option D. Kicking a soccer ball to the goal represents potential energy being converted to kinetic energy. When the ball is still on the ground, an energy is being stored in the ball called potential. However, as soon as the ball is kicked the potential energy stored is now being converted to another form of energy associated with motion called the kinetic energy.

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.
