Wave Properties |
|
|
Simple Harmonic Motion |
An object oscillates back and forth from an equilibrium point with an angular frequency (w) and is subject to linear restoring force.
|
|
Frequency |
f= 1 / time |
|
Angular Frequency |
Is the change in angle per time described by the particles path as it moves around the circle.
|
|
Pendulums |
Simple Harmonic Moti |
|
Uniform Circular Motion (Rev) |
1 Rev/ sec= Particles moving at circular path at constant speed. |
|
Springs |
w (angular frequency)= square-root (k/ m) w= sqr(k/ m) |
|
Hooke's Law |
F= -kx
|
|
Newtons 2nd Law |
F=-(k)(x) |
|
Spring Constant (k) |
Stiffness
|
|
Spring and Pendulum |
k= mg/ L |
|
Hooke Law |
When mass = equilibrium
When Oscillation= Xmas (displacement)
|
|
Point of Max Acceleration in Hooke-Law |
Acceleration is proportional to distance (x), the acceleration will be greatest when displacement from equilibrium is maximized. |
|
KNOW This- Spring Constant and Frequency |
w= sq(k/ m)= 2(pi(f) |
|
Potential Energy for Spring and Pendulum |
Mass Spring=1/k(x^2) |
|
Kinetic Energy for Spring and Pendulum |
Both are 1/m(v^2) |
|
Angular Frequency (w) for Spring and Penduclum |
Spring= sqr (k/ m) = 2pi(f)
