What are the conditions for simple harmonic motion? |
• the acceleration of the bob must act towards the equilibrium point •acceleration must be proportional and opposite to the displacement from equilibrium. (a=-w^2x) |
|
|
What is the equation(s) of displacement from equilibrium in terms of time and angular velocity |
x=Acos(wt) for starting at amplitude x=Asin(wt) for starting at equilibrium |
