C1 - Simple Harmonic Motion

• The circumference of a circle in radians is 2Πr
• angular speed is the rate of change of angel with time
• T is the time taken for 1 complete revolution
• 1 radian is 57.3 degrees Celsius
• angular speed is the angular displacement per second
• the unit for angular speed / ω is $rad s^-1$
• the amplitude (A) is the maximum displacement from the equilibrium position
• Isochronous means the period does not depend on the amplitude of the oscillations
• Velocity is given by the gradient of the displacement time graph
• acceleration is given by the gradient of the velocity - time graph
• Acceleration is directly proportional to negative displacement
• acceleration is in the opposite direction to displacement
• acceleration is always directed towards the equilibrium position
• for small angles; the angle does not affect the period
• mass does not affect the period
