... momentum is conserved. There is no initial momentum. For the net momentum to remain zero, the two momenta must always be equal-and-opposite. Defining right to be positive, and using 1 as a subscript for the ball on the left and 2 for the other ball, momentum conservation gives: , which we can simpli ...

Chapter 2 Classical Thermodynamics: The Second Law 2.1 Heat
... This is a substantial chapter, containing many important results and many techniques. There are two common technical difficulties for many students at the beginning: proof of theorems and partial derivatives. We will emphasize the understanding and applications of the theorems and we will do many pr ...

We have also observed children winding a toy (such as a toy car) and when the toy is placed on the floor, it starts moving. When a balloon is filled with air and we press it we notice a change in its shape. As ...
