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 ...

A red and a blue snooker ball both have a mass of 160 g. They collide with speeds and directions as shown in this diagram. The following steps show you how to calculate the velocity of the red ...

The quantum rules shaping molecular collisions are now coming into focus ... the advent of quantum mechanics—one of the clearest examples of quantum wave effects in molecule-surface interactions ...
