Projectile Motion and Simple Harmonic Motion

The video tutorial covers the concepts of simple harmonic motion and projectile motion. It begins with an introduction to simple harmonic motion, explaining its defining differential equation. The tutorial then transitions to projectile motion, discussing the lack of horizontal acceleration and the effect of gravity on vertical motion. An example problem is set up to illustrate the application of these concepts, followed by a detailed walkthrough of solving the equations of motion for both horizontal and vertical components. The session concludes with a practice exercise on vertical motion equations.

What is the defining characteristic of simple harmonic motion?

• Displacement is proportional to time.
