Two conditions for something to be considered to under go SHM? |
.acceleration (and there for resultant force) is always directed towards the equilibrium position .the force/acceleration is proportional to the displacement from the equilibrium position |
|
|
Displacement equation |
Displacement = Amplitude * cos(Angular velocity * Time) |
|
|
Angular frequency equation? |
Angular frequency = 2*PI * frequency |
|
|
Velocity equation? |
Velocity = +- sqrt( (Amplitude^2) * (Displacement^2) ) (Note +- is reversed) |
|
|
Maximum speed equation? |
Max speed = Angular frequency * Amplitude |
|
|
Acceleration equation? |
Acceleration = - (Angular frequency^2) * Displacement |
|
|
Maximum acceleration equation? |
Max acceleration = (Angular frequency^2) * Amplitude |
|
|
Equation for time period in a spring system? |
Time period = 2 * PI * Sqrt(Mass ÷ Spring constant) |
|
|
Equation for time period is a simple pendulum? |
2 * PI * sqrt(Length ÷ Gravitational field strength) |
|
|
Equation for time period of a vibrating cantilever(ruler)? |
Time period = 2 * PI * sqrt( ( Mass * (Length^3)) ÷ (3 * Constant * Width)) |
|
|
Equation for Time period in a u shaped test tube? |
Time period = 2 * PI * sqrt(Length ÷ ( 2 * Gravitational field strength)) Length measure from outside and around the tube |
