Oscillations are a grand topic in physics, and play a key role in many topics. For the purposes of this course, they will be included in the mechanics portion. Oscillations are such a big deal because they describe another way of moving. Up until now youve learned about linear and rotational motion, but what about the motions of waves? Think of a compressed spring that is released and how it bobs back and forth. While it may look like linear movement, there are quite a bit of math involved with that spring. For now, well concern ourselves with simple harmonic oscillators to get an understanding of how oscillators look and how their movement is calculated. After this topic, its on to the final topic of mechanics!
Simple Harmonic Motion (SHM) is motion in which a restoring force is directly proportional to the displacement of an object.
Nature’s response to a disturbance is often SHM.
Angular frequency (ω) is the number of radians per second, corresponding to an angular velocity for an object traveling in uniform circular motion.
When an object undergoes simple harmonic motion, kinetic and potential energy both vary with time, although total energy (E=K+U) remains constant.
The period of a spring-block oscillator is proportional to the square root of mass divided by the spring constant.
In analyzing a spring block system, if you find a new equilibrium position when the block is hanging on the spring, taking into account the effect of gravity, you can then treat the system with only the spring force to deal with, oscillating around the new equilibrium point.
The reciprocal of the equivalent spring constant for springs in series is equal to the sum of the reciprocals of the individual spring constants.
The equivalent spring constant for springs in parallel is equal to the sum of the individual spring constants.
The period of a pendulum is proportional to the square root of the length of the pendulum divided by the acceleration due to gravity.
