1 Physics I Oscillations and Waves
m!0Af1 cos[2(!0t+˚)]g (1.12) shows similar oscillations which are exactly ˇout of phase. In a spring-mass system the total energy oscillates between the potential energy of the spring (U) and the kinetic energy of the mass (T). The total energy E= T+Uhas a value E= m!2 0A 2=2 which remains constant.

For example, in a transverse wave traveling along a string, each point in the string oscillates back and forth in the transverse direc-tion (not along the direction of the string). In sound waves, each air molecule oscillates
