PHYS 1201W Chapter Notes - Chapter 9: Coil Spring, Angular Frequency
Document Summary
Oscillation - moving back and forth repeatedly over the same path simple harmonic. Amplitude = maximum displacement if the oscillating object from equilibrium. Cycle = a complete oscillation back and forth which returns the system to its original state. Period t =time needed for one full cycle. Frequency f = of the oscillation is the number of cycles in a unit of time. When a mass at the end of a coil spring is displaced from its equilibrium position and released, the resulting oscillatory motion is shm. This relates to f = -kx or hooke"s law. With newton"s second law a = -kx / m. If the spring is made stiffer fo k is increased, the spring oscillates more rapidly. W = 2*pi*f measured in rad/sec - angular frequency. The frequencies and periods are the same for vertical and horizontal motions. For a weight hung on a spring, w=mg. This is an object swinging back and forth.
