Final exam on December 11th Monday

Our final exam will be at 9am on December 11th (Monday) in our regular meeting room Small 111. We will cover everything except materials presented during this week (chapters 16 and 17 - Waves and Sound) also do not worry about Damped and Forced oscillators.

I am posting the final exam which was given in 2022 at BlackBoard, so you could assess its difficulty.

Note: the final exam day and time are unmovable (except for people with SAS accommodations). If you have to change the day and time you should contact the Undergraduate Dean to obtain permission.

Midterm 03 on November 13th

The midterm will cover material presented in lectures 01-26 (excluding introduction to fluids)

The sample midterm is available at BlackBoard.

Midterm 02 on October 23rd

The midterm will cover material presented in lectures 01-18 (excluding the Center of Mass discussion).

The sample midterm is available at BlackBoard.

Midterm 01

The midterm will cover material presented in lectures 01-08

Lecture notes

Lecture 36: Standing wave. String musical instruments. Relationship between speed of sound, frequency, and wavelength

Lecture 35: Wave equation. Traveling waves in ropes, speed of the wave. Boundary conditions.

Lecture 34: Physical pendulum. Meaning of the variables. Solution for given initial conditions. Examples.

Lecture 33: Solution for Harmonic oscillator equation and meaning of the labels. Simple pendulum and physical pendulum.

Lecture 32: Problems involving Bernoulli equation. Introduction to harmonic oscillator

Lecture 31: Remote study

Please watch complimentary video about resistive forces, i.e. drag and effects of viscosity. Even though in the lecture the motion of the spheres is discussed. You can think about pipes as “inverted” spheres, than you would see the connection to discussion of viscose flow in Ch14.7 of the text book. This is, by the way, your reading assignment.

By the way, I strongly recommend other lectures by Dr. Lewin.
