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 proposed by French physicist Edme Mariotte as early as 1676. When the ball on the right side swings and collides with the closely arranged four other balls on the return swing, the ball on the left will be ejected, and the ball on the 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 the velocity vr in the opposite direction. Conversely, the l-ball can move with the opposite velocity −vl, and the r-ball has the opposite velocity −vr.
Experimental Cognition
Frame: an important component of the Newton's cradle, it installs the sheep's horn nails and. Its main function is to generate lift.
Hole glass beads: A propeller is a device that converts the rotational power of an engine into propulsive force by rotating the blades in the air. It is connected to the hub by two or more blades, with the rear side of the blades being a spiral surface or approximately a spiral surface. This type of ship propulsion is called a propeller.
The propeller is divided into many types and is widely applied, such as in airplanes, ships, etc.
Experimental Procedure：
1. Experiment preparation: Recognize the experimental equipment: frame, glass beads with holes.
Experimental 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 is transferred to the r ball on the right, which is initially at rest. The r ball with mass m has the same momentum after the collision. The balls that are collided both have a velocity vr to the right and a tendency to move to the right, which is called momentum conservation.
