About it
Newton's cradle is a row of steel balls, each hung on two strings so it can only swing in one line. Lift the end ball and let go: it strikes the row, the ball at the far end flies out, and the balls in between barely move. Let go of two and two fly out.
It shows two rules of physics at once: in each knock both the momentum and the energy carry through the row, so the same number of balls leaves as arrived. Each clack turns a little energy into sound and heat, so the swings slowly die away. Drag any ball out (the balls beside it come too) and let go, or tap to lift the end ball.
