Spring-Mass System — x = A·cos(ωt)
Drag amplitude and spring constant. Watch the oscillation live.
ω = √(k/m) = — rad/s | T = 2π/ω = — s
x–t (displacement over time)
Simple Pendulum — T = 2π√(L/g)
Change length and gravity. Notice that mass doesn't affect period!
T = 2π√(L/g) = — s | f = — Hz
Energy in SHM — KE + PE = constant
Watch kinetic and potential energy trade off as the mass oscillates.
E_total = ½kA² = KE + PE = — J
KE, PE and total energy over time
Wave Motion — v = fλ
Combine frequency, wavelength, and amplitude. See the wave travel live.
v = fλ = — m/s | T = 1/f = — s
Displacement at x=0 over time
