What happens when a moving shuffleboard puck hits stationary of equal mass in head on collision?

In a head-on collision between two shuffleboard pucks of equal mass, where one is moving and the other is stationary, the following happens:

* Διατήρηση της ορμής: The total momentum of the system before the collision equals the total momentum after the collision. Since momentum is mass times velocity (p =mv), the moving puck initially has all the momentum. After the collision, the momentum is shared between the two pucks.

* Perfectly Elastic Collision: If we assume a perfectly elastic collision (no energy loss to heat, sound, etc.), the kinetic energy of the system is also conserved.

* Transfer of Momentum: In an ideal head-on collision, the moving puck will transfer all its momentum to the stationary puck.

* Final Velocities: The moving puck will come to a complete stop, and the stationary puck will start moving with the same velocity the first puck had initially. This is because the momentum and energy are equally distributed between the two pucks.

Συνοπτικά:

* The moving puck stops.

* The stationary puck starts moving with the same velocity the first puck had initially.

Σημαντική σημείωση: Real-world collisions are rarely perfectly elastic. There will always be some energy loss due to factors like friction and sound. Therefore, the stationary puck will likely gain a slightly lower velocity than the moving puck's initial velocity.
