While some are contemplating the end of the world, I am studying for physics. Here are the essential oscillations equations to know for our test tomorrow.
Oscillations (Includes SHM, Springs, Pendulums):
T=1/f and f=1/T
Potential Energy= (1/2)kA2cos2(wt)
Kinetic Energy= (1/2)kA2sin2(wt)
Total Energy= (1/2)kA2
x(t)= Acos(wt + phase shift)
v(t)= Awsin(wt + phase shift)
a(t)= -Aw2cos(wt + phase shift)
For use with pendulums only:
Also, from past units, the torque equations are handy, along with the moment of inertia equations.
