If it's a real Newton's cradle with perfectly elastic collisions, then the kinetic energy of the launched ball should be equal to the total kinetic energy of all the stuff moving after the impact.

Illustrates how kinetic energy is transferred from one body to another through elastic collisions. Explains formulas for calculating the exchange of energy. Defines concepts concerning stored ...

For this case, if the ball number 4 starts off moving with a speed v, it will collide with ball 3. After that collision, ball 3 will move to the left with a speed v and ball 4 will stop.

The kinetic energy gained in the collision was about 3 to 4 percent, which closely matches observations. The study confirms that CME collisions can be super-elastic.

The team’s study, published July 2 in Nature Physics, found that whether the condensates behave more like a viscous liquid or an elastic solid depends on the strength and duration of the amino acids’ ...

BUFFALO, N.Y. — Droplets of proteins, tied to an increasing number of cellular processes and human diseases, are known for their liquid-like ability to flow, exchange material and dissolve as needed.
