Classical Mechanics
farside.ph.utexas.edumotion of a properly bowled bowling ball consists of a combination of trans-lational and rotational motion, whereas wave propagation is a combination of translational and oscillatory motion. Furthermore, the above mentioned types of motion are not entirely distinct: e.g., circular motion contains elements of both rotational and oscillatory motion.
Basic Concepts of Kinematic-Wave Models
pubs.usgs.govThe kinematic-wave model is one of a number of ap proximations of the dynamic-wave model. The dynamic- wave model describes one-dimensional shallow-water waves (unsteady, gradually varied, open-channel flow) and consists of the continuity equation and the equa tion of motion with appropriately prescribed initial and boundary conditions.

To be be speciÞc, physical discussions are made for shallow-water waves in the sea. The results are however readily tranferable or modiÞed for sound, waves in blood vessels and other
The Seismic Wave Equation
igppweb.ucsd.eduabsence of body forces, we have the homogeneous equation of motion ρ ∂2u i ∂t2 = ∂ jτ ij, (3.9) which governs seismic wave propagation outside of seismic source regions. Gener-ating solutions to (3.8) or (3.9) for realistic Earth models is an important part of seismology; such solutions provide the predicted ground motion at specific ...

Transverse waves on a string - Harvard University
scholar.harvard.eduIn section 4.1 we derive the wave equation for transverse waves on a string. This equation will take exactly the same form as the wave equation we derived for the spring/mass system in Section 2.4, with the only difierence being the change of a few letters. In Section 4.2 we discuss the re°ection and transmission of a wave from a boundary.
Wave Energy Technology Brief
