Unformatted text preview: Oscillations 1. Different types of motion: • Uniform motion • 1D motion with constant acceleration • Projectile motion • Circular motion • Oscillations 2. Different types of oscillations: • Periodic oscillations • Chaotic oscillations A motion is called periodic when the system comes back to the same physical conditions every time interval T. • Harmonic oscillations (the simplest, the most important type of periodic oscillations) 3.
