Questions and Answers

What is the equation for displacement in Simple Harmonic Motion (SHM)?

$x(t) = A\cos(\omega t)$ (correct)

$x(t) = -\omega^2 A\cos(\omega t)$

$x(t) = -\omega A\sin(\omega t)$

$x(t) = \omega^2 A\cos(\omega t)$

What is the equation for velocity in Simple Harmonic Motion (SHM)?

$v(t) = A\cos(\omega t)$

$v(t) = -\omega A\sin(\omega t)$ (correct)

$v(t) = -A\sin(\omega t)$

$v(t) = \omega A\cos(\omega t)$

What is the equation for acceleration in Simple Harmonic Motion (SHM)?

$a(t) = \omega^2 x(t)$

$a(t) = -A\sin(\omega t)$

$a(t) = -\omega^2 x(t)$ (correct)

$a(t) = \omega^2 A\cos(\omega t)$
