Periodic motion (AQA A-Level Physics): Flashcards

Systems that oscillate following simple harmonic motion (SHM)

$T = 2\pi \sqrt{\frac{l}{g}}$

Less than $10^\circ$ (small angle approximation)

$T = 2\pi \sqrt{\frac{m}{k}}$

PE at peak, KE is zero

KE is maximum, PE is minimum

Remains constant

Gradual loss of energy to environment, amplitude decreases

Amplitude reduces slowly over time

Amplitude reaches zero in shortest time without further oscillation
