What kind of energy transformation is happening in the video?
Electrical to sound
Potential to kinetic
Kinetic to potential
Potential to thermal
Why is that the correct energy transformation?
Because the girl moves and then she goes up to a high position and stops moving.
Because the girl starts up in a high position not moving, and then she moves down.
Because the girl jumps with electricity and then screams.
