This satisfies the condition for SHM that a = -kx; in this case k = Ï2 = (2ð f)2. The acceleration of the object is directly proportional to its displacement from its equilibrium position. Objects moving with SHM, exchange between potential and kinetic energy. It is written and maintained by a fully qualified British Physics Teacher. The terms in this equation are the same as the equations above. Physics A-Level: Downloads The most comprehensive compilation of past papers grouped in categories. Email info@curriculum-press.co.uk Phone 01952 271 318 This lesson follows the AQA Physics: A Level Year 2 textbook written by jim Briethaupt. Simple Harmonic Motion (SHM) is a particular type of oscillation. AQA A-Level Physics Revision. Let x = A cos(Ït) where x, Ï and t are the displacement, angular velocity and time respectively. The velocity equation simplifies to the equation below when trying to find the maximum speed (which will be at the point of minimum displacement), The acceleration equation simplifies to the equation below when we just want to know the maximum acceleration (which is at the point of maximum displacement e.g why it uses the Amplitude of the system). Graphs of Simple Harmonic Motion: SHM Graphs. An object is undergoing SHM if: The acceleration of the object is directly proportional to its displacement from its equilibrium position. The period of oscillation is dependant of amplitude and constant. Lets think about a simple example of shm to work out the relationship between displacement, velocity and acceleration: AQA A-Level Physics/Simple Harmonic Motion. A-Level Physics revision notes, videos and more for AQA. AQA A level Physics Worksheets, exam style questions. In SHM, the frequency and period are independent of amplitude, so the time period for oscillations will stay constant even when the swing becomes very small. Booklet of questions were compiled from past paper questions from 2002 - 2009 from old scheme (This is a work in progress! At the equilibrium, all of the energy is kinetic energy.

Full Video Index. Mr Burrows is a legendary Physics teacher based in the United Kingdom. These are important notions to remember as they’re specific to SHM and allow us to determine whether an object or system does in-fact move with SHM. It is useful because its time period stays the same even when its amplitude changes. These graphs show how displacement and acceleration are proportional but in opposite directions, and also how when you have the minimum displacement, velocity is at its maximum. As the object moves towards the equilibrium, all of the potential energy gradually transfers into kinetic energy. Very useful resource for students and teachers.

Simple Harmonic Motion (SHM) is motion where acceleration is proportional to and opposite in direction to the displacement from its equilibrium position. Simple harmonic motion is any motion where a restoring force is applied that is proportional to the displacement and in the opposite direction of that displacement. ...
