Item NG002004: An inflated balloon flying around the room as the air leaves the balloon involves the transformation of elastic energy to motion energy.
Which of the following involves the transformation of elastic potential energy to kinetic energy (motion energy)?
- A rubber ball travels up into the air after being thrown.
- A clay ball falls and flattens when it hits the floor and remains flat.
- An inflated rubber balloon flies around the room as the air leaves the balloon.
- None of these involves the transformation of elastic potential energy to kinetic energy because elastic potential energy cannot be transformed into kinetic energy.
