 2018.05.14: "Thank you for doing what you do. You've gotten me through two years of physics and I only wish I had the opportunity to be one of your students. I hope that you know that you are teaching the next doctors and engineers who will each take their own impact on this world. And one of the reasons they did it and got to where they are was because of you :) Thank you so much" wayne peterson  YouTube Community Comment

Demonstrating What Changes the Period of Simple Harmonic Motion (8:22)
Period of simple harmonic motion is defined and demonstrated. Equations for period of massspring systems and pendulums are given. What changes the period is demonstrated. This is an AP Physics 1 topic.
Content Times: 0:01 Defining period, T 0:47 Demonstrating period 2:50 Period equations 4:00 Does amplitude affect T? 4:35 Does g affect T for massspring system? 4:54 Does mass affect T for pendulum? 5:40 Increase mass in massspring system? 6:01 Increase k in massspring system? 6:24 Increase pendulum length? 6:50 Increase g for a pendulum? 7:26 Does A really not affect pendulum? Thank you to Anish, Kevin, and Olivia for being my “substitute students” in this video!
