Simple Harmonic Motion
3
11-1 Simple Harmonic Motion The force exerted by the spring depends on the displacement: (11-1)
5
11-2 Energy in the Simple Harmonic Oscillator We already know that the potential energy of a spring is given by: The total mechanical energy is then: (11-3) The total mechanical energy will be conserved, as we are assuming the system is frictionless.
8
11-2 Energy in the Simple Harmonic Oscillator The total energy is And we can write: (11-4c) This can be solved for the velocity as a function of position: (11-5) where
9
11-3 The Period and Sinusoidal Nature of SHM (11-7a) (11-7b)
10
11-4 The Simple Pendulum Therefore, for small angles, we have: where The period and frequency are: (11-11a) (11-11b)

Exam 5 problems 3 Qualitative (30 points) 2 Quantitative (70 points) Suggestions – Read problem carefully – Underline important stuff, cross out extraneous stuff – Outline solution if out of time – If you think you need a quantity that doesn’t appear to you to be there, make one up. – Study Equation Sheet.
