Why do the balls of the Newton’s cradle eventually stop?

The balls of the Newton’s cradle eventually stop because they loose energy as they collide.

The balls of the Newton’s cradle lose energy to the air as they move through it due to friction.

These balls make sound when they collide, and consequently the balls loose energy to heat upon collision.

The balls loose energy as they collide with each other and eventually stop.

Thus, we can conclude that the balls of the Newton’s cradle eventually stop because they loose energy as they collide.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
