The oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position.

2. Hooke’s law is the elastic limit where the extension of a spring is proportional to the tension force. The small deformations of an object, the displacement or size is directly proportional to the deforming load.  An independent variable for the experiment can be the weight (force) added to the spring. F= E x F where (F) is force, (E) is elasticity and (K) is a constant. 

3. Gravitational potential energy and Kinetic Energy changes during pendulum movement by having the pendulum start at a high potential energy and as it falls the energy is converted to Kinetic energy, which then is used to push the pendulum back up and looses it as it falls with potential energy. Eventually friction with air slows or decreases the energy after each swing. 

4. A wave is a number of crests that move past a given point in a matter of unit in time. Frequency is measured through the units of hertz and is the length of a wave. Amplitude is the maximum displacement moved by a point on a vibrating wave. A period is the time needed to complete a cycle of vibration. 
 
5.The equation for simple harmonic motion is F=-kx.
F=restoring force, k=the sprint constant, x is displacements. and its relation to its acceleration is ma= F= -kx
m=is mass, a= acceleration.

6. A medium can be modeled by a series of particles connected by springs. 

7. A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.

8. A transverse wave is a wave vibrating at right angles to the direction of its propagation. An example can be vibrations in springs or ripples on water surface. During a transverse wave, particles of a medium oscillate in a direction of perpendicular. 

9. A longitudinal wave is a wave vibrating in the direction of propagation. Propagation is the transmission of motion, light, sound, in a particular direction or through a medium. It looks like a spring or a coil. Look at bottom for a picture.

10. Crests and troughs are apart of waves. Troughs is the lowest part of a wave length while the crest is the highest point. A wavelength is the distance between crests in sound waves or electromagnetic waves. 

11. The difference between constructive and destructive interference is that constructive interference is when two waves are added to each other and they create a force that is either one of the two waves or a combined wave with a greater amplitude. Meanwhile, Destructive interference is when two waves will phase out from one another or will combine to be a lesser wave.

(7) A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium is limited, and the material does not move far from its initial equilibrium position. 

(8) A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction the wave moves. Examples are light, a wiggling string, and ripples from a stone thrown into a pond. It's also like moving a slinky that's stretched across a room up and down, because the wave moves side to side but the slinky moves up and down.

(9) A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction the wave moves. Examples are sound waves and springs. It's also like moving a slinky that's stretched across a room side to side, because both the wave the the slinky move side to side.

2) Hooke's law is that  the extension of an elastic object is directly proportional to the force applied to it. F is the force in newtons E is the extension in meters and K is the 'spring constant' in meters
3) Mechanical energy is conserved when there's no friction. A pendulum swings back and forth and an exchange in KE occurs while its swinging.
4) Wave- a disturbance of energy that transfers energy through matter or space
Amplitude- the maximum event of a vibration or an osculation
Period- the time needed to complete one cycle of vibration
Frequency- is the number of waves passing a point in a certain time
5.For simple harmonic motion the equation is T = 2π(L / G)^ 0.5. T represents time, L represents the length of the pundulum, and G represents the acceleration of gravity. The formula for a mass spring system is  F = -k * x. F is the force applied on the spring, K is the constant, and X represents how far the spring stretches.
6) The medium carries the waves.
7) A wave in osculation of matter that transfers energy through a medium.
8) A transverse wave is a wave that moves with particles in a perpendicular motion to the direction of energy transfer. An example of this is the ripples of when a droplet of water splashes on a liquid body.
9) Longitudinal waves: Waves that vibrate in a certain direction. Motion, sound and light go through a medium.
10) A crest is the highest point of the wave and a trough is the lowest point of a wave.
11) Consecutive interference is when two amplitudes have opposite signs and create a combined wave. Destructive interference is when the sounds are different and phase out to become lesser waves.

(2) Hooke's law states that the extension of an elactis object is directly proportional to the force applied to it. F=k*e. F is the force in Newtons. K is the spring constant in newtons per meter. E is  the extension in meters. 
(3) During pendulum movement, GPE is the most at the top and kinetic energy is the most at the bottom. The kinetic energy is changed to ponential energy and vice versa. 
(4) Wave: disturbance moving through a medium. Amplitude: the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. Period: the time needed for one complete cycle of vibration to pass a given point. Frequency: the number of crests of a wave that move past a given point in a given unit of time.
(5) The equation to find period in simple harmonic motion is T = 2π(L/G)^0.5. T is time period, L is the length of the pendulum, and G is the acceleration of gravity. The formula for a mass spring system is F = -k*x. F is the force placed on the spring, k is the constant, and x is how much the spring stretches. 
(6) A medium is what the waves travel through. 
(7) A mechanical wave is an oscillation of matter that transfers energy through a medium.
(8) A transverse wave is a wave that moves with particles in a perpendicular motion to the direction of energy transfer. An example is light.
(9) A longitudinal wave is a wave that vibrates in a certain direction. An example is a coil.
(10) Crest: the point on a wave with the maximum value of upward displacement within a cycle. Trough: the displacement of the medium at that point is at a minimum. Wavelength: distance between corresponding points of two consecutive waves.
(11) Consecutive interference is when two amplitudes have opposite signs and create a combined wave. Destructive interference is when the sounds are different and phase out to become lesser waves. ]]> 2018-03-27 15:23:51 UTC https://padlet.com/tec430/swkmfkeeph7m/wish/246547690 Shreyash and Cameron https://padlet.com/tec430/swkmfkeeph7m/wish/246580793 1) Simple Harmonic Motion is an oscillatory motion under a force proportional to the amount of displacement from a equilibrium position.
2) Hooke's Law states that the applied force, F is the constant K times the change/displacement in the length X. F=K*X
3) When a pendulum swings, it goes back and forth and this is a constant change in the KE and GPE because when it swings up, KE decreases and GPE increases. When it goes down, the KE increases and the GPE decreases.
4) Wave: a movement of particles in an oscillating manner. Amplitude: Vertical distance of the wave. Period: Horizontal distance it takes to complete one cycle for the wave. Frequency: Rate at which the cycles are repeated.
5) The equation for simple harmonic motion is F=-K*X where
F=restoring force, K=the sprint constant, X is displacement and its relation to its acceleration is M*A= F= -K*X where M=mass and A=acceleration.
6) The medium in relation to waves is what the wave uses to travel.
7) A mechanical wave is a wave that is an osicllation of matter and it transfers energy through a medium.
8) A transverse wave is a wave in motion that consists of oscillations that occur perpendicular to the direction of energy transfer. 
9) A longitudinal wave is a wave that is vibrating in the direction of propagation. Some examples are springs and sound waves. They look very stretched out and high.
10) Crest: The point on a wave that has the highest value of upward displacement. Trough: The point on a wave where it is at medium and the displacement is at a minimum. Wavelength: The distance between two corresponding waves where it repeats again.
11) In Constructive Interference, the two amplitudes have opposite signs and they subtract to create a combined wave but a Destructive Interference is where the sound haves are different with one having a higher amplitude and one have a lower amplitude.]]> 2018-03-27 16:28:19 UTC https://padlet.com/tec430/swkmfkeeph7m/wish/246580793 tec430 https://padlet.com/tec430/swkmfkeeph7m/wish/247051546 2018-03-28 19:13:05 UTC https://padlet.com/tec430/swkmfkeeph7m/wish/247051546
