Chapter 4 Oscillatory Motion
www2.tntech.eduOscillatory Motion 4.1 The Important Stuff 4.1.1 Simple Harmonic Motion In this chapter we consider systems which have a motion which repeats itself in time, that is, it is periodic. In particular we look at systems which have some coordinate (say, x) which has a sinusoidal dependence on time. A graph of x vs. t for this kind of motion is shown in
Exercises on Oscillations and Waves Exercise 1
www.cpp.eduThis speed of 4 m/s is the initial speed for the oscillatory motion. Since the spring obeys Hooke’s law, the motion is one of simple harmonic (i.e. sinusoidal) withq != k=m= q 16=4 = 2 s 1. The general expression for simple harmonic motion is: x(t) = x 0cos(!t) + v 0! sin(!t) (10) For our example, x 0 = 0 since the blocks are at x= 0 at t= 0 ...

ocw.mit.eduperturbation analysis. If the sign of A is negative, oscillatory motion of ω x (and ω y) will result, and the motion is stable. Examining A = (I y−I z)(I −I xx), we see that the condition for A to be positive is that I I zz is intermediate yy between I xx and I yy.That is I

ncert.nic.inmotion of a simple pendulum is an example of a periodic or an oscillatory motion. The pendulum is said to have completed one oscillation when its bob, starting from its mean position O, moves To set the pendulum in motion, gently hold the bob and move it slightly to one side. Make sure that the string
EXPERIMENT 2 Measurement of g: Use of a simple pendulum
www.kbcc.cuny.eduSuch oscillatory motion is called simple harmonic motion. It was Galileo who first observed that the time a pendulum takes to swing back and forth through small distances depends only on the length of the pendulum The time of this to and fro motion, called the period, does not
A pendulum with a moving support point
www.phys.lsu.edu• Vertical periodic motion: Y = Y 0 cos(Ωt), X = 0. 2Y 0 cosΩt)sinθ. The motion of the support adds an oscillating component to the gravitational acceleration. This is not a driven oscillator like the previous case, because the oscillatory driving force is vertical but the natural oscillatory pendulum motion is horizontal. If Y 0Ω2 ˝ g,

www.austincc.edu• Repetitive motion through a central equilibrium point. • Symmetry of maximum displacement. • Period of each cycle is constant. • Force causing the motion is directed toward the equilibrium point (minus sign). • F directly proportional to the displacement from equilibrium. Acceleration = - ω2 x Displacement

www.deepspace.ucsb.eduCharacteristics of periodic motion • The amplitude, A, is the maximum magnitude of displacement from equilibrium. • The period, T, is the time for one cycle. • The frequency, f, is the number of cycles per unit time. • The angular frequency, , is 2π times the frequency: = 2πf. • The frequency and period are reciprocals of each other:
