Talk:A-level Physics/Forces, Fields and Energy/Oscillations

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) Understand and use the terms displacement, amplitude, period, frequency, and phase difference.
 * 2) Express period in terms of frequency.
 * 3) Define simple harmonic motion.
 * 4) Describe graphically the changes in displacement, velocity, and acceleration, during oscillations.
 * 5) Understand velocity as the gradient of the displacement-time graph.
 * 6) Recall and use a = -(2πf)2x, and the solutions x = Asin 2πft, x = Acos 2πft for simple harmonic motion.
 * 7) Describe practical examples of damped oscillations with particular reference to the effects of the degree of damping in such cases as a car suspension system.
 * 8) Describe practical examples of forced oscillations and resonance.
 * 9) Describe graphically how the amplitude of a forced oscillation changes with frequency near to the natural frequency of the system.
