BRAINCAKESimple Harmonic Motion
Revision notes for Simple Harmonic Motion in AQA Physics (7408). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- OscillationsAn oscillating object moves repeatedly one way and then in the opposite direction through its equilibrium position.
- Phase DifferenceImagine two pendulums swinging with a time period T for one complete cycle of 2 seconds.
- Simple Harmonic MotionAn object oscillates with simple harmonic motion if its acceleration is proportional to its displacement acceleration is always in the opposite…
- Simple Harmonic Motion and Circular MotionConsider an object going round in a circle at uniform speed.
- Mass-Spring SystemA mass-spring system is a trolley attached to two posts by two springs.
- A Simple PendulumThe three requirements for simple harmonic motion are: a restoring force the system has inertia and the acceleration of the bob is directly…
- Energy and Simple Harmonic MotionA freely oscillating object oscillates with constant amplitude as there are no frictional forces acting upon it.
- DampingOscillations gradually die away.
- ResonanceWhen a periodic force is applied to a system, the system undergoes forced oscillations.
