... The idea of weight being a force—a pull—is often new to students and must be stressed. You may not wish to dwell on friction to the extent presented in Section 2.1, although kinetic friction is mentioned by name in later chapters. See the interesting article “Soft Matter in a Tight Spot” by Steve Gr ...

Derivation of the One-Dimensional Wave Equation (Vibrating String)
... 1. When the string vibrates, the motion takes place in the x-u-plane (i.e. the motion is planar) and each point on the string moves in a direction perpendicular to the x-axis (i.e., we have transverse vibrations). 2. The string is perfectly flexible (or elastic). 3. The tension acts tangentially to ...
