Define Periodic Motion
Name the Force that acts to reduce displacement of an object and return the system to equilibrium.
SHM occurs when...
A general rule for SHM is:
Name two assumptions:
When an object is displaced, the spring exerts a ...... ...... equal to ....
What's the differential equation for simple harmonic motion?
What's its general solution?
Quantities: Period (T)
Frequency (f)
Angular Frequency (w)
Differentiating the general solution:
x=Acos(wt+d) gives: v=... and a=...
Phase difference of Velocity and Displacement
Velocity is maximum when...
Velocity is 0 when...
The frequency and period are related to the stiffness (k) of the spring and the particle mass; where w= sqrt(k/m)
When is the spring constant not constant?
What's the equation for the vertical displacement in equilibrium when a mass is attached to a spring?
y' for vertical oscillations is the...
Eqm Position: y.=mg/k
Hence, mg-ky.=0
Write the equation for vertical oscillations:
