What is momentum ? As defined by all writers on mechanics, it is the product of the mass of a body multiplied by its velocity. As understood by a majority of their readers, it conveys a different ...

Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon gains backward momentum.

The following steps show you how to calculate the velocity of the red ball after ... the collision was elastic or not. \(\text{total momentum before} = {\text{total momentum after}}\) ...

The Heisenberg uncertainty principle says that we cannot know both the position and the momentum of a particle at once Imagine driving a car fitted with a GPS navigation system that glitches ...
