PHYS 1500 Lecture Notes - Lecture 21: Angular Frequency
Document Summary
A mass suspended from spring is set in dimple harmonic motion. It"s found that the spring total distance of 30 cm. Returns to starting point 10 times exactly in 20 sec. what is frrequency of motion. For cylindrical spring the efffective additional mass of a light spring is 1/3 the mass of the spring. When x is maximum or minimum, velocity is 0. When x is 0 the velocity is maximum. An experiment showing a roll of paper and pencil shows the sinusoidal nature of simple harmonic motion. The spring mass system oscillates in simple harmonic motion. The attached pen traces out the sinusoidal motion. Example of a system that exhibits simple harmonic motion. The force is the component of the weight tangent to the path of motion. The motion of a pendulum is not simple harmonic motion. For smaller angles it becomes simple harmonic motion. Period is independent of the amplitude and the mass.
