For every will start on the discussions A phenomenon of oscillations a simple harmonic motion
An argument That he contrasts simple harmonic motion with that offer of free fall in America under gravity so if we have free fall under gravity there's a potential energy that increases linearly potential energy with we ever at the height of the horizontal axis and the forces Stalin ordered constant forces minus the masthead gravity and contrast forcible harmonic motion rich In this case They was Mars attached was spreading the potential energy is a quadratic function The Schulman dysfunction and other areas Proportionality between force and the deviation from the equilibrium position equilibrium position where this Potential Jews smallest The notes x 0 than measure these deviations from from eggs the euro and force There is proportional to the aviation and with the proportionality constant case spring constant so if Look at me corresponding emotion for the free fall motion it's parabola Changes with time like that and it's a time motion to the only thing that can happen is that turned out of bounds off The ground but it just falls down while the air simple harmonic motion Chaotic mulch so it looks something like this and characterizes Corroded emotional wrong equilibrium position x 0 with a B Abbott told which is a maximum deviation from X distance from here here and then have the period to our capital T which the distance from the smallest position with the smallest position or from the biggest opposition figures And finally of last constant these phase and 5 and that is the distance from the 1st maximum the origin of time equals 0 so he Some actual system that does with free fall Asked that this falling on the brevity and hitting the ground and This is really a master attached The spraying and oscillate A back-and-forth and to reiterate he'll be a potential energies It is linear program the mosque just false donned masks also laid back forth These are the 4 series Is constant Just miners and she's while the force he is proportional to the Deviation from the equilibrium position x 0 Them from radicals ever made rarely get The acceleration of The motion miners and He'll get differential equations meaning that the 2nd derivative of The deviation from the equilibrium is proportional to the aviation itself and the proportionality constant A Katie wearing red case spring constant sameness proportional with constant force and We must say so B resulting emotion he Problem which has these initial condition of the initial height and the initial velocity and curvature a mind Geo widow terms the Times Square while he'll be hair a combination of Goes Simon signed functions and they also initial conditions initial deviation from the equilibrium easier DS and initial velocity year and then we can get from this from the position of the height you can get these velocities and acceleration if we now look at those an initial conditions so let's say Tightly closed 0 Initial deviation from these equilibrium DS Initial last year and redefine athlete tool in terms of that initial conditions and that every amply tool To find Dog Initial deviation from the equilibrium square class OK times An initial velocities And redefine the angular frequency riches to Piute times frequency of 2 piles of the period and Arlinda Square was given as the ratio of And we defined the phase angle fly By these conditions that have with terms cosigned equals initial deviation from liberal position and minus 8 times size of That phase Engel its initial velocity right back on and we now use Cosigned Alpha plus beta equals cos alpha codes beta sign up signs that the trigonometric identity and We can then use those definitions and we write a position as a function of Time as well as velocity and acceleration like so so um be position The initial Was Equilibrium position plus 8 times cos only And These velocities minus 80 at times Signed only and acceleration minus a ominous gray Times a cosine only and B A minimum position suspects not mine Minus a maxim position next plus and the minimum velocity is mine is a and racks of velocity plus on the minimum acceleration minus 8 KOM and the Merrimack smaller Acceleration is case and used that bombing square equals case so let's look at an example let's look at it DNA molecules which 2 . 1 7 Michael Long the DNA molecule because of the double helix structure Uh can act like a spring so let's say the ends of the molecule becomes a singly ionized needing a negative elementary chant on 1 and deposited parliamentary and Seoul because The attraction of The negative and positive elementary charged headaches Public Felix compressors by 1 %
