The Newton's cradle is a desk demonstration device invented in the 1960s, with five identical balls fixed by a suspension rope, tightly arranged with each other. It is also known as: Newton's cradle balls, momentum conservation cradle balls, perpetual motion balls, physical collision balls, bumping balls, etc.
 The Newton's cradle was first proposed by French physicist Edme Mariotte in 1676. When the ball on the far right of the cradle is swung and collides with the closely arranged four other balls on the return swing, the ball on the far left will be ejected, and only the ball on the far left will be ejected.

The purpose of the experiment is to: 1. In a gravity system, the l ball on the left collides with the r ball on the right, which has a speed of vr. The collision follows the principles of energy conservation and momentum conservation. After the collision, the l ball moves to the right with a speed of vl, and the r ball continues to move.
Continue to move with velocity vr in the opposite direction. Conversely, ball L can move with the opposite velocity -vl, and ball R has the opposite velocity -vr.


Experimental Cognition
Frame: One of the important components of the Newton's cradle, it installs the sheep's foot nails and. Its main function is to generate lift.
Hole Glass Beads: Made from high-quality sandblasted glass, with good gravity.

Experimental steps:
1. Experiment preparation: Recognize the experimental equipment: frame, glass beads with holes.

Experiment Report:
This is a series of elastic collisions, which also include inelastic collisions and momentum. Since there are no other forces affecting the collision, the momentum of the l ball with mass m and velocity vl must be transferred to the r ball on the right, which is initially at rest. The r ball with mass m, after the collision, has the same momentum. The balls that are collided all have a velocity vr to the right and a tendency to move to the right, which is called momentum conservation.
