Osscilation

1. Simple Harmonic Oscillation

2. Energy in simple harmonic motion

3. Damped and forced oscillation

4. Resonance​

​1. Understand oscillation's quantities (displacement, amplitude, period, frequency, angular frequency and phase difference) in the context of oscillations, and express the period in terms of both frequency and angular frequency.

​​2. Understand that simple harmonic motion occurs when acceleration is proportional to displacement from a fixed point and in the opposite direction.

​​3. Interpret displacement, velocity and acceleration graphs

​4. Recall and use the equation of kinetic energy

​5. Sketch displacement-time graphs for damped force

​6. Resonance involves maximum amplitude of oscillation

Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The direction of this restoring force is always towards the mean position.

​Resonance occurs when the frequency of the driving force is equal to the natural frequency of the oscillating system. The system absorbs the maximum energy from the driver and has maximum amplitude.
