Collision/Momentum Conservation - Science Museum Exhibits Scheme
What It Shows
Exhibition items demonstrate the law of conservation of momentum to the audience through the transfer of momentum between swinging balls. Exhibition items consist of a booth with small balls hanging in a row. Small balls of the same quality are fixed by ropes and closely arranged with each other. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: When one end of the metal ball is pulled up and released, the momentum and energy obtained are transmitted to other small steel balls hanging side by side through a completely elastic collision. The outermost ball on the other end cannot transfer momentum and will be ejected.
Science Behind It
In an ideal situation, the physical process of elastic collision satisfies the conservation of momentum and energy. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. If the masses of two colliding balls are equal, then the two balls will exchange velocities after collision. If the collided ball was originally stationary, then after the collision, the ball has the same speed as the colliding ball, and the colliding ball stops.
Description
This exhibition items consist of booths, stainless steel balls, steel wires, etc.
There are * seamless stainless steel balls hanging on the crossbeam. Visitors gently lift one side of the ball, raise it to a certain height, and then put it down, source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: When the ball returns to its original position and collides, the other end of the ball will bounce up. The ball that was originally pulled up after falling is bounced up again until the energy is exhausted.
How to Take Part
Lift the small steel ball at the end to a certain height, release it, and observe the status of each swing ball.

narration
Why can other balls also move when one ball is moved?
The conservation of momentum is one of the expressions of Newton's second law, also known as Newton's pendulum. When a small ball is lifted, it has potential energy, and when it is dropped, the potential energy of the ball colliding with other balls is converted into kinetic energy, source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Remind everyone that this kinetic energy is transmitted through the middle ball to the previously stationary ball at the other end. This causes the previously stationary ball to be hit, and the kinetic energy is converted back into potential energy, repeating this process until it gradually stops due to frictional resistance and other influences.
