Identify objects undergo simple harmonic motion (with linear restoring force)
Find the solutions to SHM from Newton's 2nd law
Describe the evolution of displacement, velocity, and acceleration of an object undergoes SHM
Study the motion in simple pendulum, circular motion, and vertical oscillations
Describe and calculate the energy involved in SHM as a function of time or position


  • Familiar with Calculus 1 (limits and derivatives)
  • Familiar with Mechanics (kinematics and dynamics)
  • If you have some experience with Calculus 2 (integrals), that will definitely be helpful, but it's not absolutely necessary.



This course, Introduction to Waves: Oscillatory Motion, includes the first section you will learn in Waves and Optics, including video, notes from whiteboard during lectures, and practice problems (with solutions!). I also show every single step in examples and proofs. The course is organized into the following topics:

  • Introduction to Oscillatory Motion and Simple Harmonic Motion (SHM)

  • Solutions to SHM

  • Displacement, Velocity, and Acceleration Functions in SHM

  • Simple Pendulum

  • Energy in SHM

  • SHM and Circular Motion

  • Vertical Oscillations


Videos: I start each topic by introducing and explaining the concept. I share all my solving-problem techniques using examples. I show a variety of math issue you may encounter in class and make sure you can solve any problem by yourself.

Notes: In each section, you will find my notes as downloadable resource that I wrote during lectures. So you can review the notes even when you don't have internet access (but I encourage you to take your own notes while taking the course!).

Assignments: After you watch me doing some examples, now it's your turn to solve the problems! Be honest and do the practice problems before you check the solutions! If you pass, great! If not, you can review the videos and notes again.


  • An instructor who truly cares about your success

  • Lifetime access to Introduction to Waves: Oscillatory Motion


#1: Downloadable lectures so you can watch the videos whenever and wherever you are.

#2: Downloadable lecture notes so you can review the lectures without having a device to watch/listen.

#3: One problem set at the end of the course (with solutions!) for you to do more practice.

#4: Step-by-step guide to help you solve problems.

See you inside the course!

Who this course is for:

  • This course is intended to introduce the student to a broad range of physical phenomena involving waves (mechanical waves, sound waves, and electromagnetic waves), and geometrical and physical optics.
  • This course is for anyone who has completed high school math (precalculus) and physics (mechanics), and is interested in getting into the science field.
  • This course is for current waves and optics students who are looking for extra help outside school.
  • This course could be for anyone who is not in science stream but wants to study physics for fun.

While I was in undergrad, I was always excited to take exams because I was always well prepared and I felt accomplished after finishing each exam. I know that it is not the case for most of the students. So here, I will share my knowledge and help you to make your university life easier! :D

More about my background

I received my BSc in Atmospheric Science and Physics with a minor in Mathematics from the McGill University in 2018 and my MSc in Physics at the University of Toronto in 2019. I am currently a Ph.D. candidate in the Physics Department and I am interested in the impact of wind observation on the global predictability, Arctic climate, and weather processes.

Since my second year of undergraduate studies, I have had extensive tutoring experiences, teaching at Liberty Tutoring, as well as high school and university students through SUS Peer Tutoring and Saturday Programs. Additionally, I have been/currently am a TA for math and physics undergraduate and graduate courses.

I hope to see you in class!
