Periodic Motion
-
-
Hooke's Law
Restoring force of spring= F(spring) = F(elastic) = -kx (applied force is in the opposite direction of spring force)
-
At maximum displacement, U(spring) is maximum, KE is minimum @ At equilibrium position, U(spring) is minimum, KE is maximum
U(spring) = kx^2 / 2, KE = mv^2 /2
Physical Pendulum
-
T=2(pi)sqrt(L/g)
-
For small amplitudes, period does not depend on the amplitude

Pendumlum
Motion of a pendulum
When the pendulum is pulled back, weight x component gets larger while y component gets smaller
The greater the displacement, the larger the restoring force
For small displacement, pendulum motion is simple harmonic
Energy of a pendulum
At maximum displacement, v=0, a=largest, E=U @ At equilibrium, v=largest, a=0, E=KE
