At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for ...

As the momentum before the 'collision' is zero, the momentum after the collision is zero. In physics, this type of event is termed an explosion. Watch this video for a practical demonstration of ...

THIS book gives a very complete account of the quantum theory of collisions. In an introductory chapter, some theorems of wave mechanics are stated. The following four chapters are devoted to such ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

In collisions this means that the force of one object on the other is equal in magnitude but opposite in direction. In this example, the ball exerts a force to the right on the racquet.
