17. Ms. Simpson's science students were observing a demonstration with Newton's cradle, as shown in the
diagram below. They noticed that when the ball was raised and released on the left side, it hit the stationary balls, and its kinetic energy was transferred all the way to the last ball on the right, causing it to be propelled up. This action continued for a while, but as time went on, the balls did not go as high and eventually stopped.
Why did the balls stop moving?
The combined mass of the balls could not be overcome by the force of one moving ball.
Due to the force of gravity pulling the balls down, energy was
continually lost to the surrounding environment.
Due to air resistance and friction between the string and the
frame, some of the energy was transferred to the surroundings.
The three middle balls blocked the energy from getting to the
outside balls, so they could not rise as much.
