In Newton's Cradle, why do the spheres in the center barely move?

• Because they are not being hit directly by the outside balls.

• They have potential energy and therefore they do not move.

• Kinetic energy is transferred through them. Energy transfers from the outside balls to the inside balls.

• Thermal energy is transferred through them.
