Simple Harmonic Motion (SHM) Lab

AP Physics 1 · Unit 6: Simple Harmonic Motion

Key Objectives

Observe the $90^\circ$ ($\frac{\pi}{2}$) phase shift between $x(t)$ and $v(t)$.

Verify $a(t)$ is perfectly anti-aligned ($-180^\circ$) with $x(t)$.

Explore Mass & Spring Constant ($k$) dependency on Period ($T_s$).

Explore Length ($L$) & Gravity ($g$) dependency on Period ($T_p$).
