Newton's Cradle – Let’s Explore Different Patterns of Collisions Between the Balls!

Description :
    This page lets you try a simulation of Newton's cradle.
    Five steel balls of equal mass are suspended like pendulums in a row. This kind of setup is known as Newton's cradle. The simulation shows a top-down view of the apparatus.
    You can click and drag any of the steel balls to the left or right and then release them. The ball will try to swing back toward its original position, but it will collide with the others and create interesting motion. Try swinging different combinations of balls to see various patterns.
    In this simulation, just like in a real Newton's cradle, the coefficient of restitution between the steel balls is set to 1. A small amount of resistance is also included so that the motion gradually dampens over time.

● You can swing the steel balls by dragging any of them left or right with the mouse and then releasing them.
● You can stop the motion by pressing the [*Stop/Start*] button. After adjusting the initial setup, you can press the button again to start the simulation.
● By pressing the [Normal/Slow] button, you can view the motion in slow mode. Pressing it again will return the motion to normal speed.
● You can return to the initial state by pressing the [Reset] button.
● By unchecking the [Sound checkbox], you can turn off the collision sound effects.
  Note: In some smartphone browsers, the collision sound may not play.
