Life after Phys 111• The course material of Phys 111 has given you a taste of a wide range of

topics which are available to you as a student.

• For those of you who have an interest in gravitation/ astronomy, I suggest the following electives:– Phys 320, 321 – Astronomy and Astrophysics I and II– Phys 322 – Observational Astronomy

• For those of you interested in the biological or BME expects, I suggest the following electives:– Phys 350 – Biophysics I, Phys 451 - Biophysics II

• For those of your interested in light, optics, and photonics, I suggest the following elective which I will be teaching Fall 2014 and Fall 2015:– OPSE 301 – Introduction to Optical Science and Engineering

Why care about oscillatory motion?

Application of Total force=0 and total torque= 0 tells you that you are in static equilibrium.

Oscillatory motion is related to Stability of Equilibrium

Oscillation of a mass on a spring

Iclicker Question #2

Consider the plot of the position versus time for a particle in simple harmonic motion. When the particle is in position A, how would you describe the particles position and velocity?

A) The position and velocity are both positiveB) The position and velocity are both negativeC) The position is negative and the velocity is positiveD) The position is positive and the velocity is negativeE) The position is negative and the velocity is zero.

Iclicker Question #3

Consider the plot of the position versus time for two different masses which are oscillating while attached to a spring (assume spring constant is fixed). Which of the following statements is true:

A) Particle A has a larger mass than particle BB) Particle B has a larger mass than particle AC) Both particles have the same massD) I can not answer right now due to the earthquake.
