There are analogous notions once we include relativity or quantum mechanics, but for our present purposes the version that Galileo and Newton would have recognized is good enough: in any interaction ...

We solve problems pertaining to the Conservation of Momentum using various scenarios. In this Closer Look segment on conservation of momentum, we solve problems pertaining to the conservation of ...

Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics. A conservation law in physics describes the ...

For the students to understand the more general form of Newton's Second Law, expressed in the terminology of momentum. For the students to recognize the difference between situations in which momentum ...

In this segment, we differentiate between elastic and inelastic collisions. The conservation of momentum and the conservation of energy are explored as we do examples involving these two types of ...

A sphere moving on a smooth horizontal surface (the xy-plane) impacts a set of 13 cubes at rest on the same surface. This impacts leads to a number of subsequent impacts among these cubes. The ...
