Simple harmonic motion is oscillatory motion repetitively  that is prpoortional to displacement from the position of equilibrium.
2. Hooke's law states F= k x e where e is constant elasticity or chance and k is the rate, and f is force.
3. With a simple pendulum without friction, there is a conservation of mechanical energy so a constant exchange between KE and gravitational energy occurs.
 4.Wave is an oscillation accompanied by the transfer of energy. Amplitude is is the maximum displacement or distance moved by point on a vibrating body or wave measured from its equilibrium position. Period is the time needed for one complete cycle of vibration to pass a given point. Frequency is the number of crests of a wave that move past a given point  and unit of time.   
5.  T=2 π  √ L/g. L is the pendelum length. g is the acceleration of gravity. pendelum period. The mass spring system formula is F=kx
6. A wave medium is the substance that carries the wave or disturbance from one location to another.
7.  A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium without moving far from its initial 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. This includes ripples in the water from a rock.
9. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction the wave moves. This includes sound waves.
10. The highest point of a wave is called the crest. The lowest point is called the trough. Wavelength is the horizontal distance between waves in a series. Wavelength can be measured between two wave crests or two wave troughs.
 
11. Constructive inference is when the amplitudes have opposite signs so they substract to form a combined wave with a lower amplitude. Destructive interference is when the sound waves with the higher amplitudes sound louder than sound waves with lower amplitudes. ]]> 2018-03-19 20:55:57 UTC https://padlet.com/tec430/79z1t8a38kid/wish/243762397 Prajesh!!!!!!!!!!!!!!!!!! https://padlet.com/tec430/79z1t8a38kid/wish/243762721 1. a special type of harmonic motion where the restoring force is directly proportional to the displacement and acts in opposite direction
