1. OscillationsAn oscillating object moves repeatedly one way and then in the opposite direction through its equilibrium position.
2. Phase DifferenceImaging two pendulums swinging with a time period T for one complete cycle of 2 seconds.
3. Simple Harmonic MotionAn object oscillates with simple harmonic motion if its acceleration is proportional to its displacement acceleration is always in the opposite…
4. Simple Harmonic MotionConsider an object going round in a circle at uniform speed.
5. Mass-Spring SystemA mass-spring system is a trolley attached to two posts by two springs.
6. A Simple PendulumThe three requirements for simple harmonic motion are:a restoring force the system has inertia and the acceleration of the trolley is directly…
7. Energy and Simple Harmonic MotionA freely oscillating object oscillates with contant amplitude as there are no frictional forces acting upon it.
8. DampingOscillations gradually die away.
9. ResonanceWhen a periodic force is applied to a system, the system undergoes forced oscillations.
