Answer:
In Newton's Cradle Demonstration, converts the potential energy of one ball into kinetic energy, which is passed down the line of other balls and results of swinging the last ball upward.
Explanation:
The balls in the middle do not swing, they do move, however, because they absorb some of the kinetic energy from the left swinging ball.
The right side exterior ball moves out but not with 100% of the kinetic energy, it receives less than 100% due to interference. However, energy is transferred from the outside left swigging ball to the opposite right end ball which then swings away.
The balls that are touching in the middle cannot conduct 100% of the kinetic energy. Then additionally, gravity affects the right side swinging ball so that the kinetic it does receive through transference is affected by gravity resistance and air resistance. Thus, it swings out with less energy momentum than the left side swinging ball had coming down.
