Simple harmonic motion is the oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position.
2. The parts of a wave are period, amplitude, crest, wavelength, and trough.
3. A period is the time for a particle on a medium to make one complete vibrational cycle. Frequency is how often the particles of the medium vibrate when a wave passes through the medium. Amplitude is the maximum amount of displacement of a particle on the medium from its rest position. Mechanical waves are waves not capable of transmitting its energy through a vacuum. Medium is a substance or material that carries the wave. A transverse wave is is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. 
4. Hooke's Law is F = -kdeltaX. k stands for spring constant. 
5. (200 N/m)(6 m) = 1200 N
(52 N)/(73 N/m) = 0.71 m
6. The equilibrium position is a stable condition in which forces cancel one another. ]]> 2017-02-14 23:03:37 UTC https://padlet.com/tec430/6264babtqny1/wish/153889145 https://padlet.com/tec430/6264babtqny1/wish/153889548 1. Simple harmonic motion is a simply oscillatory motion when the net force acting on an object is elastic.
2. Parts of a wave are period, crest, wavelength, trough, and amplitude.
3. A period is the time is takes for one cycle to complete, while frequency is how often a given wave passes through a specific point. Amplitude is the distance from the resting point to the trough.  A mechanical wave is an oscillation of matter. A medium is what a mechanical wave travels through. A transverse wave travels perpendicular to the force while a longitudinal wave travels parallel to the force. 
4. Hooke's law states that stretching or compressing an elastic material requires a force that's directly proportional to the amount of stretching or compressing that's done. The k is the constant of proportionality. 
5. 
Problem 1: 
F = (200 N/m)(6 m) = 1200 N
Problem 2: 
∆x = (52 N)/(73 N/m) = .71 m
6. The equilibrium position is the position where there is no net force. ]]> 2017-02-14 23:07:51 UTC https://padlet.com/tec430/6264babtqny1/wish/153889548 https://padlet.com/tec430/6264babtqny1/wish/153890045 1. Simple harmonic motion is oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position. 
2. The parts of a wave are period, crest, wavelength, trough, and amplitude. 
3. A period is the time needed for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The frequency is the number of crests of a wave that move past a given point in a given unit of time. ]]> 2017-02-14 23:12:19 UTC https://padlet.com/tec430/6264babtqny1/wish/153890045 https://padlet.com/tec430/6264babtqny1/wish/153890276 1. Simple harmonic motion is the oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position. 
2. The parts of a wave are period, amplitude, crest, wavelength, and trough. 
3. A period is the time between a cycle starts and stops. Frequency is the is how often the particles vibrate when a wave passes through a medium. Amplitude is the the max. displacement of a  particle on the medium from the rest position. Mechanical waves are oscillations of matter. A medium is what a mechanical wave can travel through. A transverse wave travels perpendicular to a force. A longitudinal wave travels parallel to a force. 
4. Hooke's Law: F=-kdeltaX
k=spring constant
5. F=(200N/m)(6m)=1200N
 deltax= (52N)/(73 N/m) = .71
6. The equilibrium position is the the forces cancel one another out and there is no net force. ]]> 2017-02-14 23:14:34 UTC https://padlet.com/tec430/6264babtqny1/wish/153890276 https://padlet.com/tec430/6264babtqny1/wish/153890430 1. Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law
2. The parts of a wave are crest, trough, period, amplitude, wavelength 
3. Period is the time it takes to complete a full cycle. The frequency is the number of waves passed in a given second. Amplitude is the max amount of displacement a particle can have. Mechanical waves are an oscillation of matter that transform energy through a medium. Mediums are any substance that allows energy to transfer from one place to another. Transverse waves are always characterized by particle motion in relation to wave motion while longitudinal waves are when particles of the medium move in a direction parallel to the direction that the wave moves.
4. Hooke's Law states the force  needed to extend or compress a spring by some distance is proportional to that distance.
5. Problems
-(200N/m)(6m) = 1200N (Force)
-(52N) / (73 N/m) = .71m (change in distance)
6. The equilibrium position is a stable condition where forces cancel out each other, leaving no net force.

2. The parts of a wave are the amplitude, wavelength, trough, and crest.
3. The period is the time it takes for one cycle/wave. The frequency is how many times a wave/cycle passes. The amplitude is the height of the wave from the trough to the crest. Mechanical waves are waves that transfer energy though a medium (anything that propagates waves or energy) since it is an oscillation of matter. A longitudinal wave vibrates in the direction of propagation whereas a transverse wave vibrates at right angles to the direction of its propagation.
4. Hooke's law relates forces to how much a spring is stretched or compressed. 
F=-kΔx
k is the constant of proportionality (Hooke's constant or the spring constant) and is different for every situation. K is a restoring force.
5. Practice problem 1
k=200N/m 
Δx=6m
F=200 N/m x 6m= 1,200 N
Practice problem 2
k=73N/m
F=52N
Δx= (52N)(73N/m)=0.71m
6. The equilibrium position is when net force=0. ]]> 2017-02-16 01:18:01 UTC https://padlet.com/tec430/6264babtqny1/wish/154200789 https://padlet.com/tec430/6264babtqny1/wish/154711699 3. Amplitude is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. Mechanical waves is a wave that is not capable of transmitting its energy through a vacuum.  A medium is a material through with electromagnetic waves propagate. Transverse is a wave that oscillates perpendicular to the axis along which the wave travels. Longitudinal waves include sound waves(vibrations in pressure, particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave.
4. Hooke's Law is the strain (deformation) of an elastic object or material is proportional to the stress applied to it. K is the spring constant.
5. F= (6m)(200N/m)=1200N 
(52N)(73N/m) = .71
